Yes, the state of whois referrals from RIRs is a bit of a mess.

I have changed FreeBSD whois to rely more on referrals than built-in
knowledge, and this mostly works. There are a couple of hacks to cope with
awkward RIRs: AfriNIC's referrals are human-readable though they can be
parsed if you assume the rubric is fixed; for RIPE, if the netname is
NON-RIPE-NCC-MANAGED-ADDRESS-BLOCK it is treated as a referral to ARIN;
there's a similar hack for APNIC's ERX-NETBLOCKs - but evidently this
doesn't apply to more recently transferred net blocks :-(

It's probably time to make whois use RDAP under the covers for address
lookups. Bah.
