6667 - Pentesting irc
- IRC was originally a plain text protocol (although later extended), which on request was assigned port 194/TCP by IANA.
- However, the de facto standard has always been to run IRC on 6667/TCP and nearby port numbers (for example TCP ports 6660–6669, 7000) to avoid having to run the IRCd software with root privileges.
Here you can see how to connect and access the IRC using some random nickname and then enumerate some interesting info. You can learn more commands of IRC here
