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. Currently, the interface identifier is defined as 64 bits long for almost every case, leaving 64 bits for the subnet prefix. This document describes the advantages of … 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.
