We have been doing this with djbdns for years. The tinydns data files
permit suffixes (suffices?) based on the querying IP address to return
information specific to that IP range. That is a request for
support@xxxxxxxxxxx from an ip in 192.168.0.0/16 may return the private LAN
address while one from the outside world the public IP, perhaps on a
different server.

The difference between science and the fuzzy subjects is that science
requires reasoning while those other subjects merely require scholarship.
