Port Listing

TCP and UDP are transport protocols used for communication between computers, they allow your computer to communicate with other computers, over a network, in a standard manner. The grid below is a graphical representation of the first 1031 Ports (0-1031), if you move your mouse over the grid, a small label will pop up indicating the port number you are hovering over and also the service that the IANA has assigned to that port.

Some ports have more than one use, and some may be used by malicious software, so we have created a database of known associations and made it available here, if you click on any of the squares representing individual ports you will be taken to a page that shows all the information we have about that port in our database.
