Well, that's how they're listed in master files, anyway; that's the
only constraint RFC 1035 makes (see section 3.4.1).  If you're
outputting them for human consumption, you could of course output them
in some other format.  That might be surprising to some.  (It's sure
not what dig does.)  I have heard claims that some hosts on the
Internet did use other representations of v4 addresses for human
consumption.  I have never observed this.  Certainly, the wire format
is not dotted-quad, of course.

(None of this is to disagree that anything other than a 32 bit
Internet address would be ill-formed RDATA for an A record.)
