Public and Private IP Addresses
There are ranges of IPv4 Addresses that are designated for Public and Private uses.
Private Addresses
Private IP addresses that are designated for networks that have limited or no access to the Internet. Hosts or packets using these addresses as a source and destination are not to appear on the public Internet.
These private address blocks are:
10.0.0.0 – 10.255.255.255 (10.0.0.0 /8)
10.0.1.0 – 172.16.0.0 to 172.16.255.255 (172.16.0.0 /12)
10.0.2.0 – 192.168.0.0 to 192.168.255.255 (192.168.0.0 /16)
Public Addresses
Most of the addresses in the IPv4 host range are public addresses. These addresses are designed for used by hosts that are publicly accessible from the Internet. Even within these address blocks, there are many addresses that are designated for other special purposes.
