         Pros and Cons of IPv6 Transition Technologies for IPv4aaS
               draft-lmhp-v6ops-transition-comparison-00.txt

Abstract

   Several IPv6 transition technologies can be used to provide IPv4-as-
   a-service (IPv4aaS) to the customers, while the ISPs have only IPv6
   in their access and or core network. All these technologies have
   their advantages and disadvantages. Depending on several various
   conditions and preferences, different technologies may prove to be
   the most appropriate solution. This document examines the five most
   prominent IPv4aaS technologies considering several different aspects
   in order to provide network operators with an easy to use guideline
   for selecting the technology that suit their needs the best.
