Private IP address

29/05/2017 22:35

In the Internet addressing architecture, a private network is a network that uses private IP address space. These addresses are commonly used for home, office, and enterprise local area networks (LANs), when globally routable addresses are not mandatory, or are not available for the intended network applications.

These addresses are characterized as private because they are not globally delegated, meaning they are not allocated to any specific organization, and IP packets addressed by them cannot be transmitted onto the public Internet. Anyone may use these addresses without approval from a regional Internet registry (RIR). If such a private network needs to connect to the Internet, it must use either a network address translator (NAT) gateway, or a proxy server.

Private IP address ranges:

10.0.0.0 - 10.255.255.255
Addresses: 16,777,216

172.16.0.0 - 172.31.255.255
Addresses: 1,048,576

192.168.0.0 - 192.168.255.255
Addresses: 65,536
