What is the default port for IRC according to IANA?

• A. 6667
• B. 21
• C. 194
• D. 80

Answer: (C)

IRC relies on a port assignment maintained by IANA for its default, unencrypted connections. That default port has become the standard for IRC servers, meaning clients and servers expect to use this number when establishing a basic chat session. The number 194 isn’t associated with the IRC service in IANA’s registry, so it wouldn’t be the default port for IRC. Other numbers in the list correspond to completely different services: 21 is FTP, and 80 is HTTP. For encrypted connections, many servers commonly offer TLS on 6697, but the unencrypted default remains the standard port 6667.
