Validating IP Address in machine contest, howto?

[K0]

Hi all!

I have a small app that opens a port on one of its IP Addresses. The address
comes from DB Table. The problem is, if the address is incorrect, when i
pass it to a TcpListener a socketexception is raised (IP Address not valid
in context...).

Is there a way for me to check the validity of the IP Address BEFORE
actually trying to open the listener?

Thanx to Anyone answering

bye

You might try writing some "ping" code.

Here is an example that might help.
