Internet-Draft IPv4 with Adaptive Address Space June 2017
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), discusses the IPv4 public address pool expansion and the
Internet system architecture enhancement aspects. It was originated
by a study called ExIP (Extended IPv4) analyzing the use of the first
available octet (eight bits) in the reserved private network pools
(10/8, 172.16/12 and 192.168/16) to achieve a moderate address space
expansion factor of 256 by each, while maintaining their familiar
operation characteristics. Along the way, a parallel yet similar
effort, called EnIP (Enhanced IPv4), was discovered. EnIP fully
utilizes the same private network pools to increase the address space
by a factor of 17.1M with end-to-end connectivity. EzIP is a superset
that proposes one unified format for not only encompassing the
considerations of both, but also identifying additional capabilities
and flexibilities. For example, the EzIP may expand an IPv4 address
at least by a factor of 256 to as high as 256M without affecting the
existing IPv4 public address assignments, and even keeping the
current private networks intact for the 256M case. The EzIP is in
full conformance with the IPv4 protocol, and supports not only both
categories of connectivity, but also their interoperability. The
traditional Internet traffic and the IoT (Internet of Things)
operations may coexist simultaneously without perturbing their
existing setups, while offering end-users the freedom to choose one
or the other. If the IPv4 public pool were reorganized, the
assignable pool could be multiplied by 512M or even up to 2B times
with end-to-end connectivity. The EzIP may be implemented as a
software / firmware enhancement to the Internet edge routers or
private network gateways wherever needed, or simply installed as an
inline adjunct hardware module between the two, enabling a seamless
introduction. The 256M case establishes a spherical layer of routers
providing a complete interconnection between the Internet and end-
users. This configuration enables the entire current IPv4 based
Internet and private networks characteristics to remain intact. Under
the Dual-Stack environment, these proposed interim facilities would
relieve the IPv4 address shortage issue, while afford IPv6 more time
to orderly reach the maturity and the availability levels required
for delivering a long-term general service.
