Organization or individuals not meeting minimum criteria for end-user assignment as specified in ARIN end-user assignment policy may request IP space as end-user directly from ARIN if it has sponsorship of two or more ARIN subscriber members.

To be a sponsor an ARIN member must have existing business relationship with the end-user and agree that:

  1. It will act as first-level contact regarding IP requests by the end-user to ARIN and verify technical requirements for end-user according to ARIN policies

  2. If in the future the business relationship is terminated, the sponsor will notify ARIN no longer then 30 days after such an event

  3. In the event that a sponsor becomes aware that any information regarding IP block assigned under this policy is no longer valid, a sponsor must notify ARIN or verify that sponsored organization or individual has already made necessary updates to the information with ARIN. Information changes include all of the following:

End-users requesting IP block under this policy agree to the following:

  1. If in the future a request is made to ARIN for additional IP block according to this or any other policy, end-user agrees that if the new request is approved it will renumber into new IP block in 6 months or less and then return the original block received under this policy. An exception is allowed when new IP block is requested under micro-allocation policy for exchange block or other critical infrastructure.

  2. When end-user terminates relationship with one or more of its sponsors it must notify ARIN about this and in case there are less than two sponsors left, it must secure sponsorship of another ARIN member in 30 days or less. If the number of sponsors is less than two for period longer then 60 days, an end-user agrees that ARIN has the right to withdraw the assignment.

  3. An end-user is responsible with providing correct contact information to ARIN and in case of any changes such as change in legal name, physical or email address, it must contact ARIN and update the information. If ARIN becomes aware that information regarding end-user is incorrect it must contact end-user to request an updated information, assistance from sponsors maybe thought in such situations. If ARIN is unable to make proper contact with end user and the information in ARIN records remains incorrect for period of 60 days or more, ARIN has the right to withdraw the assignment.

  4. An end-user is responsible with making regular yearly maintenance fee payments according to special micro-assignments schedule to be adapted by ARIN board of trustees. ARIN will provide a renewal invoice to last known mailing address and if the payment is not received 30 days after the due date, ARIN may contact all sponsors to verify correct billing information. In the event that ARIN is unable to make proper contact with end-user or when payment is still not received 90 days after the due date, ARIN has the right to withdraw the assignment.

  5. When assignment has been withdrawn end-user agrees to make no further use of the IP block

An assignment maybe withdrawn by ARIN if it meats the criteria specified #2, #3 or #4 above or if ARIN becomes aware that any information in the original request for assignment was incorrect and otherwise end-user would not have qualified for the assignment. In such cases:

  1. ARIN must provide 30 day written notice to the last known mailing address and to all contact email addresses before withdrawing the assignment.

  2. Under special circumstances an end-user may request postponement, which can be no longer then 12 months. All decisions on these requests are to be made by ARIN staff which may ask for assistance of board of advisors. In all circumstances the decisions by ARIN are final and may not be challenged by end-user by legal or any other means.

  3. When an assignment is to be withdrawn, ARIN will provide a notice by both email and conventional mail to the sponsors and specify the reason for withdrawing the assignment and the date when it will be withdrawn.

  4. When assignment is withdrawn, ARIN will change WHOIS information to specify that assignment is no longer valid and has been withdrawn. The WHOIS data as was last known regarding end-user and the assignment must be maintained for a period of at least 6 months.

  5. An IP block assignment which was withdrawn may not be used for new assignments for at least 12 months.

All assignments under this policy must be in according with guidelines listed in RFC2050, except where other ARIN policies may take precedence. In particular one of the following is required in order to qualify for the assignment:

  1. Multihomed organizations may request a minimum assignment of /24 without any other justification; or

  2. Requesters must show exactly how previous address assignments have been utilized and must provide appropriate details to verify their one-year growth projection. The basic criteria that must be met are:

* 25% immediate utilization rate, and
* 50% utilization rate within one year

Before this policy is used a new maintenance fee schedule and other fees that are related to this policy must be adapted by the ARIN Board of Trustees. It is recommended that yearly maintenance fee schedule be scaled with 2-4 additional levels that the scale be in accordance with the size of IP block such that fee for /24 block is about 1/4 of the fee for /21 IP block. An additional one-time setup fee is also recommended to be equivalent to yearly maintenance fee.
