Used for link-local addresses [5] between two hosts on a single link when no IP address is otherwise specified, such as would have normally been retrieved from a DHCP server 172.16.0.0/12 172.16.0.0–172.31.255.255
Starting 1991-06-01, was used to map Public Data Network addresses to IP addresses. Returned to IANA 2008-01-22. This network was reclaimed by IANA in 2007 and was subsequently re-allocated in 2010. See RFC 877 and RFC 1356 for historical information. [10] 15.0.0.0/8 ARIN: 1991-09 Various registries (maintained by ARIN).
In Internet networking, a private network is a computer network that uses a private address space of IP addresses. These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments. Both the IPv4 and the IPv6 specifications define private IP address ranges.

If an ISP deploys a CGN and uses private Internet address space [2] (networks 10.0.0.0 / 8, 172.16.0.0 / 12, 192.168.0.0 / 16) to connect their customers, there is a risk that customer equipment using an internal network in the same range will stop working.
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [ 1 ] [ 2 ] IP addresses serve two main functions: network interface identification , and location addressing .
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
Private Address Space The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets: 180.92.130.239 - 10.255.255.255 (10/8 prefix) 255.255.0.0(172.16/12 prefix) - 180.92.255.255 (192.168/16 prefix) We will refer to the first block as "24-bit block", the second as "20-bit ...
blackhole-1.iana.org (192.175.48.6) blackhole-2.iana.org (192.175.48.42) prisoner.iana.org (192.175.48.1) These servers are registered in the DNS directory as the authoritative servers for the reverse lookup zone of the 10.0.0.0 / 8, 172.16.0.0 / 12 and 192.168.0.0 / 16 addresses. These servers are configured to answer any query with a ...
