Home NetworkA private network in the home that connects devices such as computers, TVs, printers, data storage, appliances, game systems, streaming media and communication tools. It is increasingly common for homes to have dozens or perhaps hundreds of devices that connect through a router. In this scenario, each device has its own private IP. network for a single geographical location such as an office that is configured to communicate internally by private IP.
Metropolitan Area NetworkA network that connects multiple locations across a city. For example, a company might set up a private network that allows dozens of offices in the same city to communicate using private IPs.
Telecom NetworksTelecom companies may use a large number of private IP addresses to address customer devices. These are then translated to shared public IP addresses by a network address translator. This approach, known as carrier-grade NAT, is employed to conserve public IPv4 addresses that are in short supply.
Cloud Infrastructure & ColocationHosts in a data center may be grouped into private networks that can communicate using assigned private IPs. In some cases, providers of cloud infrastructure or colocation charge a lower rate for bandwidth using private IPs over private networks provisioned by the provider.
NotesThe following addresses are reserved for private IP.

10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
