I suspect that Amanda was designed to use hostnames in their disklists and
.amandahosts, and names are very easy to spoof, so the lookups are done
to verify that the correct host is connecting.  I'm sure the code could be
modified to not do lookups if given an IP, but having proper DNS has many
other benefits than just helping Amanda.
   I had the same problem when I started backing up multiple sites
using a mixture of public, private, and NATed addresses.  Setting up
multiple DNS servers that could properly forward and reverse everything
(returing different addresses depending on where you were) was a bit
of a pain, but made life much easier afterwards.
