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 IoTs (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. Enabling
hierarchical address architecture which facilitates both hierarchical
and mesh routing, EzIP can provide nearly the same order of magnitude
of address pool resources as IPv6 while streamlining the
administrative aspects of it. The basic EzIP will immediately resolve
local IPv4 address shortage, 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 for providing the
availability levels required for delivering a long-term general
service.
