The IESG has received a request from the IPv6 Maintenance WG (6man) to consider the following document: - 'Analysis of the 64-bit Boundary in IPv6 Addressing' <draft-ietf-6man-why64-05.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-09-30. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-6man-why64/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-6man-why64/ballot/ No IPR declarations have been submitted directly on this I-D.
