Ctcp (version)

The CTCP version command and reply has the following command format and functions.

The Command:

/ctcp TheNick version

will return client version information about TheNick.

SYSTEM TheNick CTCP: VERSION http://www.mibbit.com ajax IRC Client .2620 
SYSTEM AnotherNick CTCP: VERSION mIRC v6.35 Khaled Mardam-Bey
SYSTEM YetAnother CTCP: VERSION Eteria IRC Client
STSTEM AndAnother CTCP: VERSION Snak for Macintosh 4.13 English
SYSTEM ThisOneToo CTCP: VERSION xchat 0.24.1 Linux 2.6.27-8-eeepc i686
SYSTEM SomeLie CTCP: VERSION Mirc
SYSTEM FunnyGuy CTCP: VERSION You could at least buy me a drink first.

and other variations, depending on the client.

If TheNick is using a Mibbit Client, the response is always sent.

• Because of the functionality of the Mibbit client, the version information is based on the Mibbit backend server, not true Client-to-Client.

It needs to be said, that some clients allow this information to be added to, with extra lines, modified in such a way to lie about the version, or even block it from responding at all.
