CNAMES and OTHER data

[Kevin Darcy]

GraniteCanyon apparently was helping you by translating that name into an
address, but I doubt that they gave any guarantee that the address would
automatically update if the underlying name was re-addressed. So it probably
never really was an "alias" in any meaningful sense of the term.

In any case, it is not RFC-legal to point an A record at a name or for a
zone-apex name to own a CNAME record. Your *only* option here is for the
zone-apex name to own an A record pointing directly to the desired address.
