[address-policy-wg] IXP pool lower boundary of assignments

While I think a /29 would be too radical (renumbering peering LANs can be a real headache, you don't want to do that more often than needed), a /26 as a default might be a good compromise. 62 usable addresses are still enough for ~70% of all IXes including 100% over provisioning. This would likely stretch the pool well into the 2030s.

Other than that, I think the current policy is fine and I wouldn't want to touch any other parts of it.

I agree, but as I also said back when 2019-05 was being discussed…

…I believe the default (and minimum) should be /29. Lavishing /25s on
IXPs with just a handful of members is really not that much better than
the /24s we currently give them.

If the ISP needs something larger than the default, there is no
problem. All it has to do is to ask for a larger assignment, just like
today.
