A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [2] (routable only within the scope of private networks, but not the global IPv6 Internet).
IPv6 addresses are classified by the primary addressing and routing methodologies common in networking: unicast addressing, anycast addressing, and multicast addressing. [1] A unicast address identifies a single network interface. The Internet Protocol delivers packets sent to a unicast address to that specific interface.
IPv6 link-local unicast address structure In the Internet Protocol Version 6 (IPv6), the address block fe80:: / 10 has been reserved for link-local unicast addressing. [ 2 ] : 2.4 Of the 64 bits of a link-local addresses' network component, the most significant 10 bits (1111111010) correspond to the IANA-reserved "global routing prefix" for ...
The Link-Local Unicast Address structure in IPv6 All interfaces of IPv6 hosts require a link-local address , which have the prefix fe80:: / 10 . This prefix is followed by 54 bits that can be used for subnetting, although they are typically set to zeros, and a 64-bit interface identifier.

The address block fc00:: / 7 is reserved by IANA for unique local addresses (ULAs). [2] They are unicast addresses, but contain a 40-bit random number in the routing prefix to prevent collisions when two private networks are interconnected. Despite being inherently local in usage, the IPv6 address scope of unique local addresses is global.
The solicited-node multicast addresses are generated from the host's IPv6 unicast or anycast address, and each interface must have a solicited-node multicast address associated with it. A solicited-node address is created by taking the least-significant 24 bits of a unicast or anycast address and appending them to the prefix ff02::1:ff00:0 / ...
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 ...
