Port Lookup

Searches a built-in reference table of 40 well-known network ports — from FTP and SSH to HTTPS, common databases, and popular dev-server defaults — showing the port number, protocol, and service name for each.

Type a port number or a service name into the search box. The table below filters as you type; clear the box to see the full list of 40 entries again.

Typing 22 filters the table down to a single row: port 22, TCP, SSH. Typing sql instead matches both Microsoft SQL Server (1433) and MySQL / MariaDB (3306), since the search checks the service name too.

A numeric query only matches a port whose number is an exact string match — searching 22 will not also surface 220 or 8022. A text query matches anywhere inside the service name, case-insensitively, so ssh, SSH, and Sh all find the same row.

The table spans classic internet services (FTP, Telnet, SMTP, DNS, HTTP/HTTPS), remote access (SSH, RDP, VNC), directory and messaging protocols (LDAP, LDAPS, IRC), common databases (MySQL, PostgreSQL, MongoDB, Redis, Oracle DB, Microsoft SQL Server), and a few common local dev-server ports like 3000 and 5000. Most rows list a single protocol, though DNS (port 53) is marked as both TCP and UDP since it uses either depending on the query.

This is a fixed, hand-picked list of well-known ports, not a live or exhaustive registry — an uncommon or organization-specific port you're trying to identify may simply not be listed. The table also doesn't check whether a port is open, in use, or reachable on any actual machine; it's a static reference only.

The entire lookup happens in your browser against the built-in list. Nothing you type is sent anywhere.
