Which port does IRC typically operate on?

• A. 6667
• B. 80
• C. 443
• D. 22

Answer: (A)

IRC uses TCP and the standard default port for IRC servers is 6667. This is the port clients typically connect to unless a different one is configured. It’s widely recognized as the classic unencrypted IRC port, which is why it’s the best answer here. While some servers offer encrypted connections on 6697, 6667 remains the conventional, most common value for IRC. In contrast, the other ports correspond to web traffic and SSH (80 for HTTP, 443 for HTTPS, 22 for SSH), not typical IRC operation.
