Xbox 360 help!!!!!!!

[6hitter]

I'm having some problems with xbox live. First xbox live couldn't connect so i tested my connection and then it says my IP address failed. I first put my Ethernet cable in my modem and it still doesn't work. I also tried my laptop but the IP address keeps on failing. I don't know what to do.

Also what is an IP address????????

if your IP configuration on Xbox is correct then you might have a firewall blocking the port
