  The existing scripts are set up to tie one domain to one home server.  As you've seen, they need updating to work with more complex situations.

  Off of the top of my head, you'll have to define home servers by IP address, and not domain name.  i.e. do the IP address lookup in the shell script, and then write out home server name / ipaddr which the actual IPv4 address.

  Then separately, have a mapping of realms to IP addresses.  That mapping can go into a database, for example.
