When designing the Internet addressing architecture, the Internet Engineering Task Force (IETF) and
the Internet Assigned Numbers Authority (IANA) have reserved various Internet Protocol (IP) addresses
and networks of various sizes (/8, /24 etc.) for special purposes or for future use.
Some are used for multicast traffic, for maintaining routing tables, for IPv4 to IPv6 translation, or to provide addressing space for public and unrestricted uses on private networks.
