ACSP Suggestion 2014.26: Sparse Allocation Apporach for IXP Micro-allocations

Suggestion

Author:

Submitted On:

Description: Suggestion: That ARIN employ a sparse allocation approach for IXP assignments out of micro allocation/CI IPv4 address space and at boundaries of /22. ARIN should publicly document that fact on its website.

Value to Community: Prevents CI from having to repeatedly and disruptively renumber when expanding.

Timeframe: Immediate

ARIN currently has a /16 of IPv4 address space, in total, reserved for micro-allocation purposes and has not used a sparse allocation method to issue from it over the past several years. The currently reserved /16 is made up of fragmented smaller blocks totaling a /16 for critical infrastructure providers, including exchange points.

We have noted there is currently an active policy proposal to expand the micro-allocation reserve block from a /16 to a /15. If the community passes this as policy, we agree using a sparse allocation approach for the newly reserved /16 would benefit IXP organizations. Therefore, we commit to using a sparse allocation approach for issuing IPv4 addresses from any newly reserved block set aside by the policy development process for IXP organizations.
