Hi All,
Is it possible to have mulitple TcpListeners on listening on the same IP address and different port?
Something like:

Dim t1 As New TcpListener("192.168.25.25", 9000)
Dim t2 As New TcpListener("192.168.25.25", 9231)
t1.Start()
t2.Start()

TIA

Hi Goran,

An IPEndPoint consists of a host and a port which can be uniquely identify
a server/service (TcpListener has another constructor that takes an
IPEndPoint parameter).

#IPEndPoint Class (System.Net)
http://msdn2.microsoft.com/en-us/library/system.net.ipendpoint.aspx
Represents a network endpoint as an IP address and a port number.

The IPEndPoint class contains the host and local or remote port information
needed by an application to connect to a service on a host. By combining
the host's IP address and port number of a service, the IPEndPoint class
forms a connection point to a service.
