:Strictly speaking, this isn't a practical problem. Situations
:where reverse and forward lookups must match (i.e. when using TCP
:wrappers) operate by (a) having an IPv4 address (b) reverse-lookupping
:it (c) forward-lookupping the result of the reverse lookup. If
:you assign multiple A records to a single domain name, you are
:breaking spec, but it doesn't cause any practical problems

I'm talking about CNAME records, not IN A records.
BTW, assigning multiple A records to a single domain does not break spec
at all. in A round robins entail other issues but none are related
to the problem of 'domain.com' vs 'host.domain.com'.
