Create separate zones on your DNS server for each internal host you need to
resolve, e.g. in named.conf put:

zone "intranet.them.com" {
  type master;
  file "db.intranet.them.com";
}

and then in db.intranet.them.com put:

@ SOA ...
  NS  ns.you.com.
  A   <address of their intranet web server>

For each host, you'll have a separate db.<hostname> file like this and a
"zone" statement in named.conf.
