[rpd] proposed policy: reservation of resources for IXPs

[Mark Elkins]

I like the proposal. I think the adjacent /24 also makes great sense.
JINX is up to 79 addresses. (http://peering.posix.co.za - summary at the
top)
I expect that once JINX is extended into Terraco, this number will go up
a fair bit.

Renumbering a peering fabric is a nightmare scenario.  It is preventable by having allocation policies which keep successful IXes in mind.
