When you connect to the Internet, there are a lot of things involved such as the HTTP, IP address and ports. In any network, the port is the endpoint of communication. All connections, whether wireless or physical end at ports. Ports are designated by 16-bit numbers that are called port numbers.

Protocols like TCP and UDP use port numbers. Every port number is associated with an IP address. It completes a network and is used for identifying the server.

You can also use the server port scan to check which ports are being forwarded most commonly. Some of the ports in your connection might be blocked by your Internet service provider.
