Forward lookups are easy - just have a different zone file for each
domain. Reverse are easy if the domains have different IP addresses,
but a problem if they do not. WEB hosting services do this all the
time. Each hosted domain returns the same IP address (if on the same
server) but reverse lookup returns the information for the WEB
server hosting the domains.

Do a lookup on infinity-ltd.com, and then on the IP address you get.

Yes, as you said: "Reverse are easy if the domains have different IP addresses,
but a problem if they do not" and therein lies my problem.  The IP addresses
are the same in the reverse lookup tables but the return domain name is not
the same as they are based on the domain name itself.

So, as I said earlier, if I do a reverse IP query, which
will be returned?  host1.domain1.com or host1.domain2.com?

So, I am trying to figure out how this is done.

Do you know how the web-hosting sites do it?

Kind regards!
Dan
