192.168.0.1: Its Purpose and Uses By Peter Garant At Isnare.com Ezine Articles

As companies began using the Internet to sort, filter and gather data, it became apparent that there was a need to develop IP (Internet Protocol) addresses that would work within the confines of a private network. During the implementation of IPv4, certain addresses were marked for this purpose, among them 192.168.0.1.

192.168.0.1 is just one of the private IP addresses that were programmed. Among the others were 10.0.0.0 – 10.255.255.255, 172.16.0.0 – 172.31.255.255 and 192.168.0.0 – 192.168.255.255.

(Note: in spite of the fact that IPv4 reserved these addresses, it still was not enough to meet the demand, and there are now efforts to implement IPv6, but it has yet to gain widespread support).

How Private IPv4 Addresses Function

Usually, a router (the computer device that transmits data packets between networks) takes the data from the Internet and sends it over to a computer. However, utilizing the Network Address Translation (NAT), the router is able to detect the packets emanating from the Internet and relay them to the proper element in the network.

Although there are other private network addresses as mentioned, it is 192.168.0.1 that is almost always set to default on network elements as manifest by the routers for D-Link and Netgear. For network managers, you can log in to http:// 192.168.0.1 and from there make the appropriate adjustments to the network, including the firewall, ports and PPPoE. You can also alter the IP address, the username and password.

Using 192.168.0.1

Depending on how your computer is set up, logging on to the site may result in a prompt asking for your username and password. If you are using applications like D-Link or Netgear, follow the instructions as stated in the user guide.

Troubleshooting 192.168.0.1

1. If you are having problems accessing the router page, check the following:

Verify that the IP address on the PC is 192.168.0.x, with the x denoting any number between 2 and 255. There is an easy way to check this if you are using Windows: go to My Network Places, and choose Properties when you right click the icon.

Now right click “LAN connection” and select Properties. Choose “Internet Protocol (TCP/IP) and go to its Properties. There you can put in the proper IP address or have one automatically selected for you. Once you have made the selection, put in 255.255.255 on the Subnet mask and 192.168.0.1 on the Default Gateway.

2. Steps to take if the IP address router has been altered:

The first thing you should do is look at the address stated in the default gateway. On Windows systems, go to Start-> Run. In the dialog box, enter “ipconfig” and click OK. Next go to the address specified in the Default Gateway (using Internet Explorer or whatever web browser you have).

Once you get to the router web interface, look for the “reset” or “factory settings” button. Depending on how the system is installed, you click and hold the button for several seconds as the router reboots, or switch off the power, press and hold the reset button, and return the power still pressing the reset button. When the router lights start coming back (they will start to blink), you may let go of the button.
