As I already indicated when this was last presented at the RIPE meeting, I
strongly support a proposal to this end. The one thing I'm missing is the
criteria for the size of the assignment - when does an IXP get a /24, /23
or a /22? With 'run out fairly' as accepted policy I don't think the
timeframes set there are in any way realistic for Internet exchanges. So,
clean as the current proposal is, I'd suggest making it a bit messier and
adding very explicit criteria.
With some first hand experience in setting up Exchanges, I would suggest
- a new IXP gets a /24
- an existing IXP that runs out of its /24 (whether from this /16 or
another range) gets a /23 and has to return the old /24
- an existing IXP that runs out of its /23 (whether from this /16 or
another range) gets a /22 and has to return the old /23
(Yes, this means renumbering every single time. Yes, it's a pain. Yes, if
you run out of a /22 for your peering LAN you're fresh out of luck.)
And while we're at it, I would suggest to add to 5.6.4:
c. Any address space that is returned by an IXP will be added to the
reserve as outlined in 5.6.2.
