How to check IP addresses a browser is connected to?

Question

I am playing a Flash-based browser game.

When I connect to the game server is there any way I can check the IP of the server, so I can ping it and check my latency?

I am using Chrome on Ubuntu 14.04 with latest Flash player.

Answer 1

This is easier:
You can list all the network connections opened by using ‘-i’ option.

lsof -i

You can also use ‘-i4′ or ‘-i6′ to list only ‘IPV4′ or ‘IPV6‘ respectively.

Answer 2

You can get a list of connections used by Chrome with lsof:

lsof | grep IP | grep chrome
