Which port is assigned to the Internet Printing Protocol (IPP)?

Explanation:
IP Printing Protocol is designed to run over HTTP, and its default listening port is 631. This port is defined in the protocol’s usage and is what most print servers (like CUPS) expose for IPP requests. While IPP can be secured or run in different contexts, the standard, widely used port for IPP is 631. The other ports are associated with SSH (22) or general web traffic (80 for HTTP, 443 for HTTPS) and are not the default port for IPP.
