WebOct 6, 2024 · The working of IPv6 relies on the following key concepts: 1. IPv6 addresses An IPv6 address uses 128 bits, four times more than the IPv4 address, which uses only 32 bits. IPv6 addresses are written using hexadecimal rather than dotted decimal, as in IPv4. An IPv6 address consists of 32 hexadecimal numbers since a hexadecimal number uses 4 bits. The management of IPv6 address allocation process is delegated to the Internet Assigned Numbers Authority (IANA) by the Internet Architecture Board and the Internet Engineering Steering Group. Its main function is the assignment of large address blocks to the regional Internet registries (RIRs), which have the delegated task of allocation to network service providers and other local registries.
