Private Address Ranges, IPv4

Private IPv4 addresses are addresses set aside by the IANA (Internet Assigned Numbers Authority) for use within

networks that will not directly communicate or not be seen by the internet. These private addresses cannot be used on the

Internet or be used to communicate with the Internet. ISP's filter out and delete packets using private IP addresses.

Any organization that uses private IP addresses on devices that communicate with the internet must use a device that

performs Network Address Translation.

Anyone can us private addresses and they are not required to seek permission to use them. Again, networks using private

IP addresses cannot communicate directly with the internet.

There are three blocks of addresses that are set aside by IANA for use in private internets and are not publicly routable on

the global internet:

Private Class A Range:

Private Class B Range: 172.16.0.0

Private Class C Range: 192.168.0.0

It is important to note that only some of the 172.xx.xx.xx and the 192.xx.xx.xx address ranges are designated for private

use. The remaining addresses are public and can be routable via the global Internet.

More information regarding private addresses can be found at http://www.iana.org and https://www.arin.net
