Three simple steps
How to Look Up a Port Number

Read the filtered table
The table updates as you type and lists the matching ports with their service name and purpose.
Use the port
Copy the port number into your firewall rule, docker run command, security group or client connection string.

Security reminder: this page is a reference only. A port number tells you which service normally listens there, not what is actually running on your host. Always confirm with a local check before opening a port on a public interface.

A Reference That Keeps Out of the Way
No popups, no signup, and the whole table is already in the page you loaded.
Instant filtering
Results narrow as you type, so one or two digits are often enough to find the port you want.
Grouped coverage
Web, mail, remote access, database, messaging and big data services are all included.
Local and private
Searching happens in your browser. Nothing you type is sent to the 73hi server.
Works on mobile
The table scrolls horizontally on small screens, so the reference is readable on a phone.
Questions and answers
Common Network Ports FAQ
Is this port list free?
Yes. The port reference is free with no signup and it runs entirely in your browser.
How many ports are listed?
The reference ships with 45 widely used ports covering web, mail, remote access, database, messaging and big data services.
Can I search by service name?
Yes. You can search by port number, service name such as SSH or Redis, or any words from the description.
What is the difference between TCP and UDP ports?
TCP establishes a connection and retransmits lost packets, which suits web, mail and database traffic. UDP is connectionless and faster, which suits DNS queries, streaming and real-time traffic. Port numbers are separate namespaces for each protocol, so TCP port 53 and UDP port 53 are different ports.
Which ports should never be exposed publicly?
Database and administration ports such as 3306 for MySQL, 5432 for PostgreSQL, 6379 for Redis, 27017 for MongoDB and 3389 for Remote Desktop should stay behind a firewall. If remote access is required, restrict it to known addresses or place it behind a VPN or an SSH tunnel.
Is my search sent to a server?
No. The port table is part of the page and the filtering runs with JavaScript in your browser, so nothing you type leaves your device.
