Abstract
The IPv6 unicast addressing format includes a separation between theprefix used to route packets to a subnet and the interface identifierused to specify a given interface connected to that subnet.Currently, the interface identifier is defined as 64 bits long foralmost every case, leaving 64 bits for the subnet prefix. Thisdocument describes the advantages of this fixed boundary and analyzesthe issues that would be involved in treating it as a variableboundary.
