IPv6 addresses are each 128 bits long. Because each digit in an IPv6 address can have 16 different values (from 0 to F=15), each digit represents the overall value of 4 bits (one nibble), with 32 digits total. As with IPv4, CIDR notation describes ranges in terms of a common prefix of bits.

IPv6 addresses are numeric labels used to identify and locate a network interface of a computer or network node participating in a computer network using IPv6. Unicast and anycast addresses are typically composed of two logical parts: a 64-bit network prefix used for routing, and a 64-bit interface identifier used to identify a host's network interface. Multicast addresses are formed according to several specific formatting rules, depending on the application, and are composed of a prefix field with the binary value 11111111.

Internet Protocol version 6 is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion, and is intended to replace IPv4. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017.

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.

In IPv6 there is a special "Unique Unicast" IP range of fc00::/7 which should be used for this as per RFC4193 . The official definition looks like this:
