If you connected your PC to your modem (and the modem is bridged or not doing any NAT), your ISP would assign your PC a public IP address, which would look something like 93.184.216.34. In our analogy, the phone number is like the IP and the option is like the port number. If it got a packet to 31.13.65.36 :21, it would have its FTP server application deal with it. The server using 31.13.65.36 sees that request is on port 80, so it has its HTTP server application handle that request. Your browser knows to send HTTP requests to servers using port 80, so it sends out a packet to a server to request a website. For example, the HTTP protocol expects to receive traffic on port 80 and FTP expects port 21 (you can see a comprehensive list here). You know when you call a phone number and the auto attendant picks up and says "Press 1 for sales, 2 for billing, 3 for support"? It's kind of like that.Įvery application which expects to receive requests from the outside world uses a designated port number so it knows how to handle that request.
