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,
with 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.

This document is a product of the Dynamic Host Configuration Working Group of the IETF.

This is now a Proposed Standard.
