Quote:
Because of concerns over the growing shortage of IP addresses, there is a special set of IP addresses that have been set aside by the Internet Assigned Numbers Authority (IANA) for private networks. These addresses will not be assigned to any system connected to the global Internet.

IANA has reserved the following three blocks of the IP address space for private networks:

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
