Abstract Abstract
The IPv6 unicast addressing format includes a separation between the The IPv6 unicast addressing format includes a separation between the
prefix used to route packets to a subnet and the interface identifier prefix used to route packets to a subnet and the interface identifier
used to specify a given interface connected to that subnet. used to specify a given interface connected to that subnet.
Currently the interface identifier is defined as 64 bits long for Currently the interface identifier is defined as 64 bits long for
