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.<br>
<br>
Value to Community: Prevents CI from having to repeatedly and
disruptively renumber when expanding.<span style="font-family:

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.<br>
<br>
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.<span
