Ipv6 addresses are 64 bits long
WebAn IPv6 address is 128 bits in length and consists of eight, 16-bit fields, with each field bounded by a colon. Each field must contain a hexadecimal number, in contrast to the dotted-decimal notation of IPv4 addresses. In the next figure, the x's represent hexadecimal numbers. Figure 3-2 Basic IPv6 Address Format 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.

http://www.steves-internet-guide.com/ipv6-guide/ 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. The IANA has maintained the official list of allocations of the IPv6 addres…
WebThe IPv6 unicast addressing format includes a separation between the prefix used to route packets to a subnet and the interface identifier used to specify a given interface connected to that subnet.

With IPv6, addresses are 128 bits long. One reason for such a large address space is to subdivide the available addresses into a hierarchy of routing domains that reflect the Internet's topology. Another reason is to map the addresses of network adapters (or interfaces) that connect devices to the network. IPv6 features … See more A flexible routing mechanism is a benefit of IPv6.
