Usage Guide
Features
Lists IANA-registered common port numbers and service information, covering Well-Known ports (0-1023), Registered ports (1024-49151), and Dynamic ports (49152-65535), making it easy for developers and ops to quickly look up service port numbers and protocols. Search uses fuse.js for fuzzy matching.
Steps
Enter port number, service name, or description keyword in the search box for real-time fuzzy matching; use the "Type Filter" dropdown to filter by well-known, registered, or dynamic ports; click the copy button on the right to copy the port's complete information (port number, protocol, service name, description).
Notes
This table only includes commonly used service ports, not the full IANA registry; some ports support both TCP and UDP (e.g., DNS port 53), separated by "/" in the protocol column; the same port number may correspond to different services in different environments. Please judge based on your actual environment.
