IANA Service Name and Transport Protocol Port Number Registry - TOML

The IANA Port Number Registry is the official assignment list of port numbers used in network communications, managed by the Internet Assigned Numbers Authority (IANA). Port numbers range from 0 to 65535 and are categorized into three groups: System Ports (0-1023), User Ports (1024-49151), and Dynamic/Private Ports (49152-65535). Each port number is used in combination with specific transport protocols such as TCP, UDP, SCTP, and DCCP, and is essential for identifying standardized services like HTTP (80), HTTPS (443), and SSH (22).
