WebBoth IPv4 and IPv6 addresses come from finite pools of numbers. For IPv4, this pool is 32-bits (2 32) in size and contains 4,294,967,296 IPv4 addresses. The IPv6 address space is 128-bits (2 128) in size, containing … An IPv6 address consists of 128 bits. [1] For each of the major addressing and routing methodologies, various address formats are recognized by dividing the 128 address bits into bit groups and using established rules for associating the values of these bit groups with special addressing features. See more An Internet Protocol Version 6 address (IPv6 address) is a numeric label that is used to identify and locate a network interface of a computer or a network node participating in a computer network using IPv6 See more IPv6 addresses are classified by the primary addressing and routing methodologies common in networking: unicast addressing, anycast addressing, and multicast addressing. A unicast address identifies a single network interface. … See more General allocation The management of IPv6 address allocation process is delegated to the Internet Assigned Numbers Authority (IANA) by the See more On system startup, a node automatically creates a link-local address on each IPv6-enabled interface, even if globally routable addresses are … See more An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits The groups are separated by colons (:).
