4. Every pc that accesses the internet needs a unique ip address to communicate with other devices online. For xp users, double click the network icon in the system tray and click on the status tab, or click on start, run and type ‘CMD’, from the command prompt type ipconfig and hit enter. For win 9x do the same but ype COMMAND instead of CMD. If your pc connects directly to the internet, this reveals the true ip assigned by your isp. If you connect via a router or another network, it shows the internal ip assigned by the local network, usually beginning 192.168.
