Private IP Ranges

Private IP Ranges

Private IPs are reserved for local networks and are not routable on the public internet.

The three private ranges (IPv4)

Range	CIDR	Example
10.0.0.0 – 10.255.255.255	/8	10.0.0.12
172.16.0.0 – 172.31.255.255	/12	172.16.5.42
192.168.0.0 – 192.168.255.255	/16	192.168.1.42

Which one should you use?

• 192.168.x.x is most common for home networks
• 10.x.x.x is common for larger or more complex networks

Netory tip

Use private ranges consistently so your IP documentation stays clean and predictable.
