associating subdomains to .net sockets

[radiax]

Is there a way to associate or bind a subdomain to a tcp sockets under .net
framework (vb.net / c#). I know ip address can be used when using sockets,
but the problem is the ip address is shared among subdomains (limited ips
supply). Iam looking for possible way to use subdomain.domain.com instead of
ip address. Any inputs??
thanks

What do you mean by "shared"?

you can use "subdomain.domain.com" but then in order to do any network i/o
you will
have to query your DNS server for the server ip address. ( because sockets
work only with ip addresses )

to obtain needed ip address

Dns.GetHostByName("subdomain.domain.com"); ( .NET 1.1 )
or Dns.GetHostEntry("subdomain.domain.com"); ( .NET 2.0 )

when i say shared i meant that the box has only one ipaddress and all
subdomains share that ip.

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.
