How to check which programs from your PC are connecting to which servers on the internet

Have you ever wonder which program on your PC are currently connected to the internet? Well, you don’t even need to install any new program to figure that out.

Windows XP and above have already got the built-in command line program called netstat, which can give you a lot of useful network related information. Just follow these steps:

• Start Menu –> Run –> cmd
• Type : netstat –b, for me I got the output like :

TCP LT-SV505:4661 65.55.57.252:http ESTABLISHED 4760
[chrome.exe]

TCP LT-SV505:3091 ip-167-34-219-155.ip.secureserver.net:23396 ESTABLISHED 4388
[Skype.exe]

From the output, I can know that currently Skype and Chrome are connecting to the internet from my PC. But remember, netstat command will give you a lot of other system processes that are connected to the internet as well. Make sure you Google each process name before ringing any alarm bell.
