Locate My IP

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. This is good and helps to keep IP addresses available, prior to IPv6.


The downside to this is that private IP address ranges are considered
non-routable. That is, 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 Address

Many network devices, such as Linksys routers, use 192.168.1.1 as their default
IP address.

This can create difficulties, because two devices on a network cannot share one
IP address, otherwise you will definitely have an IP Address Conflict issue. 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 networks
which both use the 192.168.1.1 IP address.

When adding a new device to your network, be certain that its default IP
address is not already in use on your network.

Defined in the Internet RFC's

192.168.1.1 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:

    * 10.0.0.0 - 10.255.255.255 (10/8 prefix)
    * 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
    * 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

These are some other Private IP Addresses in Common Use:

    * 192.168.0.1
    * 192.168.2.1
    * 172.16.0.1
