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
A public IP address is a globally routable unicast IP address, meaning that the address is not an address reserved for use in private networks, such as those reserved by RFC 1918, or the various IPv6 address formats of local scope or site-local scope, for example for link-local addressing. Public IP addresses may be used for communication ...

The Internet Assigned Numbers Authority (IANA) is a standards organization that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol–related symbols and Internet numbers.
The allocation of IP addresses is important for several reasons. Public addresses need to be unique; if duplicate internet addresses existed on a network, network traffic could be delivered to the wrong host. The RIRs make sure that public addresses are given to one organisation. The RIPE NCC does this for its own service region.
At the top level, the IP address pool is managed by the Internet Assigned Numbers Authority (IANA). The total IPv4 address pool contains 4 294 967 296 (2 32 ) addresses, while the size of the IPv6 address pool is 2 128 ( 340 282 366 920 938 463 463 374 607 431 768 211 456 ) addresses.
