Technical Summary:
The 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 this fixed boundary and analyses
the issues that would be involved in treating it as a variable
boundary.
