ops v6ops IPv6, Transition Technologies, Comparison, IPv4aaS, IPv6-only, 464XLAT, DNS64, Dual Stack Lite, Lightweight 4over6, MAP-E, MAP-T Several IPv6 transition technologies have been developed to provide customers with IPv4-as-a-Service (IPv4aaS) for ISPs with an IPv6-only access and/or core network. All these technologies have their advantages and disadvantages, and depending on existing topology, skills, strategy and other preferences, one of these technologies may be the most appropriate solution for a network operator. This document examines and compares the performance of some free software implementations of the five most prominent IPv4aaS technologies (464XLAT, Dual Stack Lite, Lightweight 4over6, MAP-E, MAP-T).

IETF has standardized several IPv6 transition technologies and occupied a neutral position trusting the selection of the most appropriate ones to the market. provides a comprehensive comparative analysis of the five most prominent IPv4aaS technologies to assist operators with this problem. This document adds one more detail: performance analysis and comparison of the examined IPv4aaS technologies. Currently this document is a stub. It has been created to provide a citable reference for the above mentioned I-D.
