I know. The problem is that if there are several hosts with different
domains / subdomains, there will be needless lookups, wasting time and
bandwidth (perhaps not a lot of it, but still). Even worse, say I
control 'foo.dynalias.org' and 'bar.dyndns.org', but someone else
controls 'foo.dyndns.org' and 'bar.dynalias.org'. Then regardless of
which subdomain is first in 'resolv.conf', I'll get incorrect matches,
which is obviously totally unacceptable. At this point, I have various
workarounds for my needs (so far I only need ssh anyway, so I can just
use ssh aliasing, as in my earlier posts), but I'm still really curious
about a general, reasonably elegant solution.
