Are all 172 IP addresses private?
Note that only a portion of the “172” and the “192” address ranges are designated for private use. The remaining addresses are considered “public,” and thus are routable on the global Internet. Use caution when setting filters to exclude these private address ranges.

What are the three private address ranges which can be used by an organization without getting them reserved?

- 172.16. 0.0 to 172.31. 255.255.
- 192.168. 0.0 to 192.168. 255.255.
What is the purpose of private addresses RFC 1918 )?
RFC 1918 describes the use of IP address space deemed private by IANA, the Internet Assigned Numbers Authority (see, for example, RFC1918 – Address Allocation for Private Internets for details). Private address space is available for use by any organisation and is guaranteed to be not routable in the public Internet.
Which set is the correct 1918 address range?
The RFC1918 address space includes the following networks: 10.0. 0.0 – 10.255. 255.255 (10/8 prefix)
What is a private IP address range?

What IP address blocks are reserved for private IP addresses?
The Internet Assigned Numbers Authority (IANA) reserves the following IP address blocks for use as private IP addresses: 1 10.0.0.0 to 10.255.255.255 2 172.16.0.0 to 172.31.255.255 3 192.168.0.0 to 192.168.255.255
What is a non-routable IP address?
Class B: 172.16.0.0to 172.31.255.255 Class C: 192.168.0.0to 192.168.255.255 An IP address within these ranges is therefore considered non-routable, as it is not unique. Any private network that needs to use IP addresses internally can use any address within these ranges without any coordination with IANA or an Internet registry.
How many IP addresses can be assigned to one IP address?
The Internet Assigned Numbers Authority (IANA) reserves the following IP address blocks for use as private IP addresses: The first set of IP addresses allow for over 16 million addresses, the second for over 1 million, and over 65,000 for the last range.
