Networking Guide - Finding a Default Gateway / IP Address

In fact, this default IP address can enable you to access the administrative functions easily when you have set up the router for the first time. So, it is highly important to know this IP address for this reason.
As the way, the default IP address of the NetGear router is 192.168.01 and this is the private address and so it can only be used locally. However, the NetGear router can obtain the other public address when it is connected to the internet.
