AFAIK most you can get is a prefix-list per aut-num with the extended whois
whois -h whois.radb.net \!gas2914
gives you all of the registered prefixes for AS 2914. If you want to have
the same data for a given macro you have to first resolve the macro. E.g.
whois-h whois.radb.net \iAS-VERIO,1
which recursively resolves all of the macros within AS-VERIO.
I do this for the DE-CIX routeservers once a day to compile as- and
prefix-lists. While as-lists may be useful I guess most of the prefix-lists
are more or less useless. E.g. prefix-list has 10k entries whereas the
actual announcement is about 1k prefixes.
