[arin-ppml] Draft Policy ARIN-2014-7: Section 4.4 MicroAllocation Conservation Update - Revised

For those who are concerned about making sure these types of blocks are
available in the future, there are two other avenues which could be
explored beyond what is proposed in this policy.

1. Increase the size of reserved block which ARIN is holding for

2. Remove the /24 minimum for IXP allocations.  Since there is no
technical reason to have an IXP block be a /24 and the operational best
practice is to not route these blocks we could look at "right sizing"
IXP blocks rather giving a very small IXPs a rather large block for what
they need.  Yes, this brings up the possible renumbering issue in the
future, but a /25 or /26 still allows quite a number of IXP participants. 

Do operators have any thoughts on these ideas?

It's hard enough for rural service providers to pool enough funds to buy a switch and stand up an IX, discouraging them from building additional interconnectivity by making it difficult to get IP addresses is disappointing.
