  What's with the trailing dot at the end of the LHS (left hand side)
of the second record?

  The above two records -- as given -- likely describe two different
domain names.

  The first record's LHS is a relative name <faxcore1.mwro>.  You
don't give the origin, but if the origin is <aspca.org.>, then the
FQDN would be <faxcore1.mwro.aspca.org.>

  The second record's LHS is an FQDN <faxcore1.mwro.>.  Full stop,
nothing more.  So the top-level domain (akin to <com.>) would be
<mwro.>, which is not registered.  It's very unusual to have that in a
public-facing DNS server.  It generally doesn't work.

  Is that dot really there?  Or is it a typo in your transcription?
