Besides 192.168.1.1, another private IP address that is commonly used is 192.168.2.1, and like the other private IPs, its purpose is to preserve the data that goes through it.
The 192.168.2.1 Infrastructure
As with any other computer device, IP address 192.168.2.1 makes use of routers to relay information to and from the Internet to the network node. Aside from using the NAT (Network Address Translation), the router includes a public IP address. This is what the computers on the network use as identifiers when going through the Net.
Using 192.168.2.1 Correctly
It should be made clear that only qualified network systems administrators should have access to 192.168.2.1 properties and their functions, as making any changes to them can have an effect on the computers integrated with the network. Similarly, any attempt to resolve any difficulty or problems with this IP address should be left to the administrator or to qualified/assigned personnel.
For making custom changes, one has to go to http:// 192.168.2.1 and after entering the necessary information, one can make the necessary changes. If problems are encountered, the place to begin troubleshooting would be (in Windows operating systems), the My Network Places, and the properties associated with it, such as LAN and TCP/IP.
There may come a time when the routers have to be reset to their default status. The procedures vary, depending on the routers. For 192.168.2.1, the router is usually Belkin; if that is the case, then you would need to press/hold the button for 7 seconds, after which the settings will be set back to default.
Troubleshooting Belkin Routers
If you are having problems getting to this default adress with a Belkin device, try turning off firewalls, or enable the IP address (making sure that the IP specified is the correct one). If you press the reset and nothing works, try holding it down for several seconds and it will reset. Then have your firmware CD in hand, as the process for installation will begin.
After the re installation is complete, you can set up the security features; remember that this is a task you must set up yourself. As is always the case when handling routers, make sure that the instructions are followed step by step.
192.168.2.1 and Broadband Routers
192.168.2.1, while the frequent IP address on network computers, is also the default for some home based broadband routers as well, and it is often utilized to make contact with the default gateway (usually 255.255.255). It should be noted though, that 192.168.2.1 can be changed to another IP address if the user or person in charge so desires.
If you are having problems accessing this IP address, disable any firewalls that might be in place, as this can cause a conflict with 192.168.2.1. If the firewall has been disabled, or there isn't one installed, go to Internet Explorer, and click Tools, Options. Click “LAN settings” in the Connection tab, and then remove all check marks.
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.
