NICKSERV

Also: NICKSERV | NS

NickServ allows users to register their nicknames for use while online. Users may reserve their favorite online name for their personal use with options to ensure that nobody else can use it. After registration, users can PROTECT their nickname from use by others so that services will automatically change their nickname, or you can manually change someones nickname by using the RECOVER command. If a user does not use a registered nick for the number of days set in the services nickname configuration, the registered nickname expires and becomes available for registration by other users.
