hi guys
i am going through some msdn sample packages.

i am trying to connect to the tcpclient. ( chat program on sockets)

this works fine if i use "localhost" but i want this to connect over the internet

i am getting the error 'No such host is known'

VB Code:
  1. Dim serverIP As IPAddress = ipaddress.Parse("X4.X5.XXX.36")

  2.  

  3.         client = New TcpClient("serverIP", PORT_NUM)

if anyone can see any possible problems please let me know,
