[ size:big normal small ]
I. Purpose and Scope of Application
The Measures are formulated by China Internet Network Information Center ("CNNIC") in accordance with the national regulations and relevant policies of Asia Pacific Network Information Center ("APNIC") with a view to promoting the effective allocation and administration of resources like IP addresses and AS Number in China.
The application for resources including IP addresses and AS number, etc from Address Allocation Alliance of CNNIC and the reallocation and assignment of obtained resources shall comply with the Measures.
The application for resources including IP addresses and AS number, etc from Address Allocation Alliance of CNNIC and the reallocation and assignment of obtained resources shall comply with the Measures. 
 
II. CNNIC IP Address Allocation Alliance
CNNIC became a member of APNIC in January 1997 as the National Internet Registry of China and initiated the IP Address Allocation Alliance, providing allocation and administration service of IP address and AS Number for ISPs and those enterprises and public institutions in need of large amounts of addresses in China. 
Membership of CNNIC IP Address Allocation Alliance is a prerequisite for application for IP address and AS number, etc from CNNIC. 

 
III. Description of the Terms
i. Allocation Window of the Alliance Member
Allocation window of the Alliance Member is administrated by CNNIC, used to limit the maximum address space directly allocated or assigned by the Alliance Member without the review and approval of CNNIC.

If the IP address quantity applied for by the user of the Alliance Member is equal to or less than the allocation window of the Alliance Member, there is no need to submit the user’s application to CNNIC for review.The initial allocation window of each Alliance Member is 0, and the allocation window will be expanded as the Alliance Member accumulates experience and improves technology in terms of address allocation. 

ii. Second Opinion
If the Alliance Member that obtains IP addresses from IP Allocation Alliance plans to allocate to its users an address quantity that is larger than its allocation window, it needs to submit a form to CNNIC with a detailed description about how to allocate and assign the addresses. The Alliance Member cannot allocate addresses to its users until CNNIC has reviewed and approved ofapproved the form and it needs to complete relevant database registration.
 
iii. Internet Registry
An Internet registry is an organization that allocates IP addresses to its members or users and registers them accordingly.

iv. Address Allocation IP Address allocation means allocating the addresses to internet registries which will then allocate them to downstream organizations. 

v. Address Assignment
Address assignment means allocating the addresses to the internet infrastructure of Internet Service Provider (“ISP”) or to the terminal sites. The assigned addresses cannot be further assigned. 

vi. Terminal site
A terminal site is an organization whose upstream ISP provides internet access service, allocates IP addresses and provides routing and which has no downstream sites. 

vii. HD ratio
HD ratio is a way to measure the utilization rate of IPv6 addresses. The calculation formula is as follows: 
     
             Log (address space already allocated)
         HD ratio = ----------------------------
              Log (maximum address space available for allocation)
The address space above means the corresponding number of addresses of /48. 
  
viii. Point-of-Presence
PoP is an access point to the internet and it must have an exclusive IP address. Both ISP and online service provider have points-of-presence to the internet, and the number of points-of-presence is sometimes an indicator of the size and growth rate of service provider. 

ix. Autonomous System
Autonomous system is a group of networks that use the unified internal routing agreement. 

x. Redemption period
The member of IP Address Allocation Alliance can continue to use the address normally if they pay renewal fees within 1 month after the expiration date as stipulated in the IP Address Allocation Alliance Agreement. 

Within the redemption grace period from the second month to the third month after the expiration date as stipulated in the agreement, CNNIC puts the addresses in the public address pool and deletes the registration information of this address. If the member of IP Allocation Alliance intends to continue to use this address within the redemption grace period, it must pay the relevant fees and the term of use after redemption begins from the expiration of the term of the original agreement. 

Upon the expiration of the redemption grace period, this address will be returned to the global IP address allocation organization and the member of IP Allocation Alliance will be deprived of the right of use of this section of address. 

IV. Principles of Address Allocation Observed by CNNIC IP Address Allocation Alliance
i. Exclusivity
The allocation of addresses is globally exclusive. While the resources are allocated to the Alliance Members, CNNIC registers the resources in the global address database to ensure the exclusivity of the allocation. 

ii. Aggregation and Reservation
The IP addresses should be allocated on a hierarchical basis according to the network structure, which facilitates address aggregation and limits the length of global routing table. CNNIC will allocate to the applying Alliance Members the addresses that they need recently (normally a year) according to their actual demands and will reserve a continuous range of address spaces to meet the requirements of the Alliance Member for development, but it will not reserve a large block of addresses. 

iii. Routing
CNNIC is a state internet registration organization of China and is not responsible for the address routing and broadcast. 

iv. Rent of Addresses
The IP internet addresses are globally exclusive. As stipulated in the policies of APNIC and CNNIC, address allocation is an act of renting instead of an act of permanent sale or transfer; therefore, the Alliance Member need to pay relevant fees timely to ensure it can continue to effectively use these resources. 

V. Application for the Membership of CNNIC IP Address Allocation Alliance
The applying organization submits the stamped membership application form and photocopies of business license and access bandwidth certificate as well as corresponding written description to CNNIC. After CNNIC reviews them, the applying organization will sign the IP Allocation Alliance Agreement with CNNIC and pay relevant fees to become a member of the CNNIC IP Address Allocation Alliance. 

VI. Application for and Allocation of IPv4 Addresses
i. Application Processing Processes
The Alliance Member that apply for an address larger than /21 need to fill out Application Form of IPv4 Address, and those applying for a portable address larger than /24 and less than /21 for internet exchange or small ISPs with multiple exit points need to fill out Application Form of Small Block of Portable Addresses. 

ii. Initial Allocation
First-time applicant of IPv4 address should submit an address application form (Application Form of IPv4 Address or Application Form of Small Block of Portable Addresses), network topology, list of equipment and network development plan by email to CNNIC.
 
First-time applicants of IPv4 addresses should fill out the column of “network-plan” on the address application form, describing its address planning. The applicant that has never applied for an IP address from other upstream ISPs does not need to fill out the column of “cust-network” or “infrastructure” on the form. 
  
The prerequisites for the Alliance Member to apply for an IPv4 address larger than or equal to /21 initially are as follows: 

The member is using or about to use the address of /23 obtained from its former upstream ISP. 
The member has reasonably used the address obtained. 
The member plans to use an address of at least /22 within a year. 
The member plans to return the address obtained from its former upstream ISP. 
The members who apply for an address larger than /21 must have made a plan to use an address of at least /22 within a year. CNNIC usually allocates an address of /21 as the enabling address. 
  
The conditions for the Alliance Member to apply for small block of portable addresses initially are as follows: 
The member should have a plan to use 25% of the addresses it applies for within the near future and 50% of the addresses it applies for within a year. 

The member plans to return the address obtained from its former upstream ISP. 
If the member that has obtained small block of portable addresses intends to apply for more addresses, it needs to return the small block of portable addresses it has obtained. 

iii. Subsequent Allocation
When the utilization rate of the IPv4 addresses it has obtained reaches 80%, the Alliance Member may apply for new IPv4 address to CNNIC. 

When the utilization rate of the IPv4 addresses it has obtained is less than 80%, the Alliance Member must demonstrate that the address quantity it intends to apply for is larger than the remaining address quantity it now has with sufficient data and plan.
 
When the Alliance Member applies for IPv4 address for the second time, it should submit an address application form to CNNIC. It must fill out the columns of “cust-network” and “infrastructure” on the form and demonstrate that the utilization rate of IPv4 addresses has reached 80%, and the information filled in the column of “cust-network” should be registered in whois database of APNIC. 

iv. Allocation and Assignment of IPv4 Addresses to the Alliance Members
The initial allocation window of each member of Address Allocation Alliance is 0. The Alliance Member with an allocation window of 0 is required to submit Second Opinion to CNNIC before each allocation or assignment of address, and it is not allowed to make official address allocation until the CNNIC approves and it should also make registration in the whois database. The member is not allowed to allocate or assign address if CNNIC does not approve.
 
The allocation window will be expanded as the Alliance Member accumulates experience and improves technology in terms of address allocation. After the expansion of allocation window, the allocation of addresses less smaller than allocation window may be made directly by the member with no need to be reviewed by CNNIC, and the allocation of addresses larger than allocation window still requires the review of CNNIC. 

CNNIC has a right to require the Alliance Member to submit detailed description of the use of IP addresses and to register in WHOIS, and the member should cooperate.
 
The allocation and use of IPv4 addresses should comply with RFC2050 and highly-efficient use of the addresses should be ensured. Meanwhile, the use of IPv4 addresses should observe the following principles: 
  
Static allocation of addresses in a dial-up server is not allowed. 
Named-based virtual host rather than IP-based virtual host is used. 
The PC in the normal LAN uses private address. 

v. Reverse DNS Delegation 
After the receipt of Application Form of Reverse DNS Delegation submitted by the Alliance Member, CNNIC may provide Reverse DNS Delegation for allocated IPv4 address with /24 or /16 as a unit. 

VII. Application for and Allocation of IPv6 Addresses
i. Application Processing Processes
CNNIC reviews the application materials submitted by the Alliance Member and submits them to APNIC for review after it reviews and approves ofapproves it. After APNIC reviews and approves ofapproves it, CNNIC will allocate addresses to the Alliance Member.
 
ii. Initial Allocation
The Alliance Member that plans to provide IPv6 connection to the users, provide address assignment to at least 200 users within two years, and broadcast this connection via its own single aggregate address meets the standards for initial allocation and will be allocated IPv6 addresses of /32. If the Alliance Member can provide convincing documents proving that the allocation of more addresses will be appropriate for the existing number of users and scale of network structure, it may possibly get a initial allocation of more than /32.

iii. Subsequent Allocation
If the utilization rate of IPv6 addresses of the Alliance Member meets the evaluation standard that the HD ratio should be bigger larger than or equal to 0.94, the Alliance Member may obtain a quantity of IPv6 addresses equal to the previous quantity. If possible, the Alliance Member will be allocated an address adjacent to the previous one, meaning that the total address prefix is extended by one digitbit to the left. If the Alliance Member needs to apply for more IPv6 addresses, it needs to provide documents to certify its demand for IPv6 addresses within two years, and CNNIC will allocate appropriate addresses based on the documents.
 
iv. Allocation and Assignment of IPv6 Addresses of the Alliance Member
1. Sub-allocation of addresses by the Alliance Member to downstream ISPs
The Alliance Member may frame the policy for allocation of addresses to its downstream ISPs so as to optimize the use of obtained IPv6 addresses. The downstream ISPs must register all the assigned addresses of /48 to facilitate the evaluation by CNNIC/APNIC when it applies for more addresses next time in the future. 

2. Address assignment by the Alliance Member to terminal sites
2.1 Size of the assigned address
The assigned address is generally /48 unless for big users. According to the network planning, the assigned address can be /64 when only one subnet is needed and there is only one available, and the assigned address can be /128 when there is only one connecteding device.

2.2 Allocation of multiple /48s to a site
If a single site needs to apply for an assignment greater than /48, it needs to submit to CNNIC supplementary materials corresponding to its application materials.

2.3 Address assignment for network structure of network operator:
The Alliance Member may assign IPv6 address of /48 to each PoP as network structure without taking into account the number of users of this PoP. 

3. Registration of allocated or assigned addresses
Allocated or assigned IPv6 addresses must be registered in public database with /48 network as a unit. When a unit is assigned more than /48, the organization that gives the assignment must register the information in Whois database of APNIC. 
CNNIC will measure the HD ratio based on the information registered in the database when the organization applies for addresses next time. 

v. Reverse DNS Delegation
CNNIC may provide reverse domain name delegation of allocated IPv6 addresses upon the receipt of Application Form of Reverse DNS Delegation submitted by the Alliance Member.

VIII. Administration and Allocation of AS Number
i. Autonomous System No.
If the member organization intends to use external routing protocols such as BGP (Border Gateway Protocol) for the network router that has multiple gateways, it may apply for autonomous system Number (AS Number). 

If the network has only one gateway, static routing or other routing protocols may be used. Under such circumstances, AS Number is not needed. To decide if AS Number is needed, the member organization may refer to RFC1930 or consult an expert. 

ii. Application Conditions
To apply for AS Number, the Alliance Member must meet all the following conditions: The network of Alliance Member has two or more gateways; the Alliance Member has signed an agreement with ISP (the other party) on the connection using BGP; the Alliance Member plans to set up mutual BGP together with one ISP within one month with the obtained AS Number and set up BGP together with two or more than two ISPs within three months. 

iii. Application Processing Processes
The Alliance Member that meets the application conditions can submit the above application materials and AS Number application form to CNNIC which will allocate the AS Number after reviewing the materials.

iv. Registration of AS Number
CNNIC registers the allocated AS Numbers in APNIC whois database. 

If the Alliance Member does not use the AS Number within three months after obtaining it, CNNIC will amend APNIC whois database and withdraw the number. 

IX. Transfer of IP Address and AS Number of the Alliance Members
The Alliance Members shall not transfer IP address or AS Number to each other unless consented to by CNNIC. CNNIC also forbids the transfer and sale of network infrastructure-independent IP addresses. Where an Alliance Member needs to transfer the network as well as the IP addresses and AS Number it uses by reason of change to its organizational structure, etc, the transferor and transferee shall submit the address transfer application bearing the official stamps of both parties and a description of the reasons for transfer. After CNNIC reviews and approves ofapproves the transfer, the address transferor shall follow the address return process and the annual fee unused within the validity period of the agreement shall not be refunded. Where the address transferee is an Alliance Member, address allocation and charging shall be conducted in accordance with the subsequent application process for the Alliance Members; where the transferee is not an Alliance Member, address allocation and charging shall be conducted in accordance with the address application process for new Alliance Members. 

X. Way of Dealing with the Address in Redemption Grace Period
CNNIC will ask the Alliance Member to make payment 30 days prior to the expiration date of allocated address stipulated in IP Address Allocation Alliance Membership Agreement by email and 15 days prior to such date by registered letter. The Alliance Member may continue to use the address normally if it makes payment timely within one month after such date. If the Alliance Member fails to make payment when the said period ends, the address redemption grace period starts, and during such period CNNIC will put the address in public address pool and delete the registration information in the database. The IP Allocation Alliance Member needs to pay relevant fees (refer to Instructions on Fees of IP Address Allocation Alliance of CNNIC for details of charging standards) if it intends to continue to use the address during the redemption grace period, and the term of use after redemption of the address starts from the expiration of the term of use stipulated in the previous agreement. 

CNNIC will cancel the membership of the Alliance Member that fails to make payment for or redemption of the address within three months after the address use period expires as agreed in the agreement and will not accept any redemption of the address thereafter. For the Alliance Member that owes CNNIC a payment for the use of the addresses but still uses the IP addressm, CNNIC will expose its information on relevant websites and take any and all legal action including but not limited to filing a lawsuit.
The loss incurred due to CNNIC’s failure to get in touch with the Alliance Member caused by the Alliance Member’s untimely notification to CNNIC of any change to its contact information shall be borne by the Alliance Member. 

XI. CNNIC’s Administration of the Alliance Members 
CNNIC will keep tracking after the address is allocated to the Alliance Member. 
CNNIC will ask the Alliance Member to submit the description of its use of the address from time to time.
If the Alliance Member fails to use the address in accordance with the administrative regulations of CNNIC, CNNIC has the right to take action. 

XII. Cancellation of the Alliance Membership
The Alliance Member's membership will be cancelled under the following circumstances: 
i. if the Alliance Member does not need to continue to use resources like IPv4 and IPv4 addresses and AS Number due to reasons attributed to itself and has submitted official application to CNNIC; or
ii. if the Alliance Member does not comply with the relevant national laws and regulations and APNIC regulations when using the address allocated by CNNIC or makes huge profits with such address; or
iii. if the Alliance Member refuses to give a description of its use of the IPv4 and IPv6 addresses to CNNIC or refuses to register in WHOIS database as requested by CNNIC;or
iv. if the Alliance Member refuses to pay or delays paying the annual use fee for the address, etc for no reason. 
After the membership is cancelled, the address allocated to the Alliance Member will be taken back, the records in WHOIS database will be deleted and the Alliance Member’s upstream ISP will be informed. 
XIII. CNNIC has the right to amend these administrative measures in accordance with relevant national regulations and APNIC regulations. 

XIV. These administrative measures are subject to the interpretation of CNNIC and come into force as of January 1, 2008. The Administrative Measures for Address Allocation Alliance of CNNIC effective as of March 29, 2004 will be abolished at the same time.
