FAQ

How many ports does this tool include?
This tool includes 200+ commonly used ports, covering well-known ports (0-1023) and common registered ports (1024-49151).
Do I need an internet connection to use this tool?
No. All port data loads with the page, and queries run entirely in your browser.
What is the difference between TCP and UDP?
TCP is a connection-oriented reliable protocol, while UDP is a connectionless fast protocol. Some ports support both (e.g., DNS port 53).
Why do some ports show multiple common uses?
The same port may be used by different software or services, so common usage scenarios are listed together.
How do I distinguish well-known ports from registered ports?
Ports 0-1023 are well-known ports, typically used by system services. Ports 1024-49151 are registered ports, typically used by user applications.
