In addition to the above, one could use "hierarchical" AS-SET names, in
some databases (from the top of my head: APNIC, AfriNIC, RIPE) only the
owner of the ASN can create AS-SETs under that ASN's namespace. But more
importantly: using the ASN in the AS-SET name chances of collision are
reduced. Example: I defined "AS15562:AS-SNIJDERS" in the RIPE database,
instead of "AS-SNIJDERS". Same for "AS2914:AS-GLOBAL" in NTTCOM.

Coincidentally, I'm working to define something like "AS-SETs in RPKI".
There are a number of downsides to "AS-SETs in IRR": collisions between
databases can exist, it is hard to figure out what AS-SET to use for
what ASN (we rely on service order forms, peeringdb or guessing for
that), and the way the recursion was done can too easily result in
gigantic sets.

I'd be interested to know what others think about improving feature
parity between IRR and RPKI, and while doing that make the bad aspects
of AS-SETs go away and keep the good parts. Thoughts?

Kind regards,
