I'm apparently having a hard time reading this month :-/ But your
point makes the problem yet worse, since there's no sense that in the
CS net class here the RDATA of an A record is a host address.  I
suppose that, since it's in 882 (which is obsoleted) that doesn't
matter.  But in CH according to the definition it's not just a host
addressm but "a domain name followed by a 16 bit" address.  (Maybe
that actually means that the domain name is not in the RDATA.  Since
I'm having so much trouble reading this month, it's probably better
that I not form an opinion.)

Thanks for the correction.
