What is a Network Port Lookup Tool?

A Port Lookup Tool provides a reference guide for standard TCP and UDP port assignments designated by IANA for network services including web servers, databases, mail agents, and remote access protocols.

How to use it

  1. Type a port number (e.g. 22 or 3306) or protocol keyword into the search bar.
  2. Inspect transport layer protocols (TCP/UDP) and standard security usage.
  3. Use the port references when opening firewall ports or configuring network security groups.

SEO & Web Development Applications

Auditing open ports on web servers ensures that only required secure services (like HTTP 80 and HTTPS 443) are exposed, preventing unauthorized database exposure and server security vulnerabilities.
