Which port is officially assigned to IPP?

• A. 80
• B. 443
• C. 631
• D. 6310

Answer: (C)

You're being tested on the port assigned to IPP, the Internet Printing Protocol used for printing over a network. The official port for IPP is 631. This is the standard TCP port defined for IPP in the IANA registry and is what printers and IPP clients typically use by default for IPP traffic. Some deployments may expose IPP over HTTPS on port 443, but the primary, officially assigned IPP port is 631. The other options map to different services: 80 is for HTTP, 443 is for HTTPS, and 6310 is not a standard IPP port.
