ARIN should make an effort to allocate and assign IP blocks so that allocations and assignments of the same size (such as micro-allocations, small, middle, large IP blocks) are made of the same /8 block as much as possible. In cases of allocations and assignments smaller then current minimum allocation size for ISP subscriber members (so called micro-allocations and micro- assignments), these allocations and assignments should be made from the IP block specifically reserved for micro-allocations and assignments. Minimum size allocations and assignments for each /8 block should be listed on the ARIN website and with additional information about the blocks where micro-allocation and assignments are made.

ARIN should request new /8 blocks from IANA at least 6 months in advance of expected need and allow at least 4 months wait period between the time it received the block and first allocation or assignment that is made out of new /8. After IANA has made an assignment ARIN should provide information regarding new IP block and expected minimum allocations and assignments to be made out each /8 block ARIN has received to ARIN announcement mailing lists, network engineering mailing lists as well as send email to technical contacts for all ISP subscriber members and end-users regarding this new IANA assigned block. An additional announcement should be made one month or less prior to first assignment or allocation. If complaints are received by ARIN regarding routability problems with new IP block, ARIN may make additional announcements on mailing lists as needed and all complains received by ARIN regarding operational issues with new IP allocations and assignments should also be forwarded to proper regional mailing list (such as NANOG). When changes are made in the future regarding minimum allocation or assignments from any /8 block, additional announcement must be made at least 30 days prior to first smaller size assignment or allocation.
