Abstract
This document describes a solution to the Internet address depletion
issue through the use of an existing Option mechanism that is part of
the original IPv4 protocol. This proposal, named EzIP (phonetic for
Easy IPv4), outlines the IPv4 public address pool expansion and the
Internet system architecture enhancement considerations. EzIP may
expand an IPv4 address by a factor of 256M without affecting the
existing IPv4 based Internet, or the current private networks. It is
in full conformance with the IPv4 protocol, and supports not only
both direct and private network connectivity, but also their
interoperability. EzIP deployments may coexist with existing Internet
traffic and the IoT (Internet of Things) operations without
perturbing their setups, while offering end-users the freedom to
indepdently choose which service. EzIP may be implemented as a
software or firmware enhancement to Internet edge routers or private
network routing gateways, wherever needed, or simply installed as an
inline adjunct hardware module between the two, enabling a seamless
introduction. The 256M case detailed here establishes a complete
spherical layer of routers for interfacing between the Internet fabic
(core plus edge routers) and the end user premises. Incorporating
caching proxy technology in the gateway, a fairly large geographical
region may enjoy address expansion based on as little as one ordinary
IPv4 public address utilizing IP packets with degenerated EzIP
header. If IPv4 public pool allocations were reorganized, the
assignable pool could be multiplied 512M fold or even more. EzIP will
immediately resolve local IPv4 address shortages, while being
transparent to the rest of the Internet. Under the Dual-Stack
environment, these proposed interim facilities will relieve the IPv4
address shortage issue, while affording IPv6 more time to reach
maturity and to provide the availability levels required for
delivering a long-term general service.
