There seems to be some confusion here.  Both localhost.com and myisp.com
are registered domain names, belonging to other people.  They shouldn't
really be used as names for your machines. ra.myisp.com itself resolves
to 64.38.103.192.

That is because that is the name the owners of localhost.com have chosen
to have it resolve to.  Localhost != localhost.com

Ideally, use a domain you own for your internal DNS, or, as long as the
machine is not answering queries coming in from the Internet, make up a
domain like internal.intranet or mydomain.moc.  I have tried using TLDs
as internal-only domains, but they don't work very well.  Some programs
expect name.ext and don't like www.lan or user at lan, with lan. as the
local-only TLD.
