Connect to it and type: //echo -a $network
That will tell you what the network name is. AFAIK, there will still be one regardless if the network is private. If it really is $null, then you can use $server instead, but for any networks with multiple servers, you'd have to either define them all in your IF statements or use wildcards if possible. Or, again, you can include the nick when using the /server command to connect.
