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. -- Dr.-Ing.

As per my analysis, there has been a ~40% increase in IXPs world-wide over the last three years (see my initial mail). Given that number, I don't think we should wait and continue wasting space with too large assignments until 2027.
I agree, but as I also said back when 2019-05 was being discussed…
IMHO, the default assignment should be something like /25.
…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. Tore
