The IESG has received a request from the Dynamic Host Configuration WG (dhc) to consider the following document: - 'Dynamic Allocation of Shared IPv4 Addresses' <draft-ietf-dhc-dynamic-shared-v4allocation-06.txt> as Proposed Standard 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 2015-05-06. 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 This memo describes the dynamic allocation of shared IPv4 addresses to clients using DHCPv4. Address sharing allows a single IPv4 address to be allocated to multiple active clients simultaneously, each client being differentiated by a unique set of transport layer source port numbers. The necessary changes to existing DHCPv4 client and server behavior are described and a new DHCPv4 option for provisioning clients with shared IPv4 addresses is included. Due to the nature of IP address sharing, some limitations to its applicability are necessary. This memo describes these limitations and recommends suitable architectures and technologies where address sharing may be utilized.
