All home broadband routers have a default, private IP address set by the router manufacturer for administrative purposes and as a gateway for home networking. Several manufacturers, including Netgear, D-Link and ZyXEL, use 192.168.0.1.
With a private IP address like 192.168.0.1, users can only access the address from within a home network. As with public IP addresses, a user can plug 192.168.0.1 into a browser’s address bar, but the page loads the router’s graphical user interface instead of a Web page.
On the 192.168.0.1 page, users can typically troubleshoot a modem problem and make administrative changes like change the router’s factory default password when setting up a home network.
As 192.168.0.1 isn’t the only IP address used in this fashion by router manufacturers, a router user might find out that his router has a default, private address of 192.168.1.1 or IP 192.168.2.1. These designations obviously follow the same nomenclature system as the 192.168.0.1 IP address.
If a user is uncertain about whether his router’s IP address is 192.168.0.1, he can search it in his browser. He can also use the IPCONFIG command at the Windows command prompt to reveal the Windows IP Configuration details including the default gateway. To perform this check, a user opens the command prompt and types “ipconfig” (without quotation marks) at the > prompt. 192.168.0.1, or another address, then appears on the Default Gateway line.
