What Is My IP:

Private IP Address belongs to the private IP address space - ( ).

A private IP address is, in contrast to a public IP address, not allocated to a specific organization, but can be used by anyone without approval from a regional Internet registry. Private IP addresses can only be reached within a closed network and are not directly accessible from the outer Internet. On the one side this is considered a security enhancement because an external Internet host cannot directly communicate with an internal host. On the other side this works again IPv4 address depletion as many companies and individuals only need a single public IP address from their ISP, and still can access the Internet with more than one computer, smartphone, or other Internet connected devices simultaneously. To find out what external IP address your router is using please go to the My IP page.

IANA has allocated the subnet for private use in February 1996 as noted in RFC 1918. It's a series of 256 contiguous class C networks with a prefix length of 8 bits each and spans 65,536 ( 256 * 28 ) IP addresses ranging from to If you want to learn more about IP subnetting we encourage you to take a look at our subnet calculator.

Network routers usually offer a configuration interface that is accessible via web browser on a URL like or or through a router specific host name alias. Below you will find a list of routers that use as the default IP address get access to its configuration interface.
