Yes if the Network provides NickServ.
Basically, the way it works is, you register your nickname with a password and an email address. Now everytime you come back to the network, you will be asked to identify yourself using a simple command. This will make sure that you hold on to your nickname and nobody steals it on you.
The command to register usually is...
/msg nickserv register PASSWORD EMAIL
You must replace PASSWORD with a password of your choice and EMAIL with a VALID email address. It must be valid as some networks like you to verify it exists by sending you an email. Once you have registered your nick, when you come back to the network you must identify yourself, you can do this with these commands..
/msg nickserv identify PASSWORD
OR
/nickserv identify PASSWORD (should work, does on most networks)
Replace password with the password that you used to register your nick. Now all you have to do is NOT forget your password.
