Which port corresponds to IRC Common Alternative?

• A. 6667
• B. 113
• C. 515
• D. 389

Answer: (A)

Understanding which port maps to a common service helps you recognize typical network traffic. For IRC, the widely used non-encrypted connection port is 6667. This is why it’s the best answer: many IRC networks designate 6667 as the standard port for clients to connect when TLS isn’t used, making it the commonly expected port for IRC traffic. The other ports point to different services—113 is for ident, 515 is for the line printer daemon, and 389 is for LDAP—so they aren’t associated with IRC.
