Google for sockets, network connect etc.

Try to establish a connection to a service running on the other system or use the Ping Class (System.Net.NetworkInformation)[^].

Note that both methods may not work when filtered out by firewalls.

With Windows you can also use the Net view[^] command. Without any options it will display a list of computers in your current domain. But execution requires usually some time and you have to resolve the system names to get the IPs.
