## Basic Information

IRC, initially a **plain text protocol**, was assigned **194/TCP** by IANA but is commonly run on **6667/TCP** and similar ports to avoid needing **root privileges** for operation.

A **nickname** is all that's needed to connect to a server. Following connection, the server performs a reverse-DNS lookup on the user's IP.

Users are divided into **operators**, who need a **username** and **password** for more access, and regular **users**. Operators have varying levels of privileges, with administrators at the top.

**Default ports:** 194, 6667, 6660-7000
```
PORT     STATE SERVICE
6667/tcp open  irc
