Re: associating subdomains to .net sockets

With HTTP, subdomains/multiple hostnames for same IP address are enabled by
using a "Host Header" tag in the HTTP headers. That allows ONE service
(W3SVC) to respond differently to browser requests depending on the Host
Header sent by the client. All of the requests go to the same IP address on
the same port (80).

You would need to incorporate some similar mechanism in the protocol you use
for the service that is listening on service port on the shared IP address.
