192.168.1.1 is an IP address in the private IP address range 192.168.0.0 - 192.168.255.255. Private IP addresses are special, because they can be utilized over and over again on different networks. In other words, both you and I can have 192.168.0.0/16 networks at the same time. The downside to this is that private IP address ranges are considered non-routable. That is to say, private IP addresses cannot communicate on the Internet without the use of Network Address Translation (NAT). RFC 1918 defines three private IP address ranges:
192.168.1.1 as a Default IP AddressMany network devices, such as LinkSys routers, use 192.168.1.1 as their default IP address. If you have a LinkSys router and you have not changed the default IP address, you can connect to it by opening http://192.168.1.1 in your web browser. The use of 192.168.1.1 as a default IP address by multiple hardware manufacturers can create difficulties, because two devices on a network cannot share one IP address. In other words, although you can have one device on your network at the IP address 192.168.1.1 and I can have a different device on my network at the IP address 192.168.1.1, neither of us can have two devices on our network which both use the 192.168.1.1 IP address. For example, if you have a LinkSys wireless router using the 192.168.1.1 IP address, you cannot buy another LinkSys wireless router and use it on the same network unless you change the IP address of one of the devices. When adding a new device to your network, be certain that its default IP address is not already in use on your network.
192.168.1.1 Defined in the Internet RFCs192.168.1.1 is officially defined in RFC 1918: Address Allocation for Private Internets: The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:
