Pick a local domain name that you're pretty sure is unlikely to exist.
It's best if it's at least two levels deep.  e.g. ".local.bakerlocal".
(Even better if it's a subdomain of a domain you actually own.)
See if it exists in DNS by looking for a SOA record:
  host -t soa local.bakerlocal.
If you don't get a "does not exist" error, pick a different one.

Then edit /etc/resolv.conf and /etc/hosts (and possibly other places; it's 
been a while since I used something based on Red Hat).  Change all 
instances of "localdomain" to your chosen domain name.

Once you do that, a lookup of your local machines in DNS won't give you a 
bogus IP address.
