IPv6 deployment growth continues throughout the world as the Regional Internet Registries assign their last remaining IPv4 addresses, and APNIC, Akamai, and Google publish IPv6 deployment statistics showing growth in both individual networks and in countries all around the globe. The standardisation work in the IETF continues to reflect this operational experience, and both the IPv6 Operations (v6ops) and IPv6 Maintenance (6man) Working Groups will be meeting at IETF 94 in Yokohama this week.
The draft draft-jjmb-v6ops-unique-ipv6-prefix-per-host has been generating significant discussion on the v6ops mailing list recently, which aims to address certain issues related to IPv6 deployment in community wi-fi scenarios. This document will be discussed in the first v6ops session on Monday morning, along with other drafts concerning the operational implications of extension headers in IPv6 packets and how and where such packets are being dropped.
Other drafts up for discussion include a proposal for identifier-locator IPv6 addressing to support network virtualisation, as well as operational recommendations for networks to assign multiple IPv6 addresses to end hosts to support usage of virtual machines, tethering, identifier-locator addressing and privacy amongst other applications. An informational draft provides advice on routing-related design choices in IPv6 networks, and there’s a proposed update of RFC 6145. The second v6ops session during Monday evening is rounded off with presentation of work to improve classification and measurement methods for IPv6.
The 6man working group will be meeting on Wednesday morning and will be discussing proposed updates to the IPv6 specification, addressing architecture and neighbour discovery as currently defined in RFC 2460, RFC 4291, and RFC 4861.
It’s not all ‘business-as-usual’ though, as Homenet Working Group will on Tuesday morning be continuing its work to produce protocols for residential networks based on IPv6. This is usually one of the best attended working groups and at this session will be focusing on autoconfiguration, naming architecture and service discovery, as well as multiple interfacing support in home-type scenarios.
There has also been much discussion on the Internet-of-Things (IoT) recently, and quite aside from IPv6 being a necessity for future scalability, the IETF has been looking into the issues of implementing IPv6 on nodes with limited power, memory and processing resource that are characteristic of IoT. The IPv6 over Networks of Resource-Constrained Nodes (6lo) Working Group will be meeting on Thursday morning, but other groups have also been investigating the related challenges of using low power and lossy networks as typically found with power line or low bandwidth radio links. It’s therefore worth checking out the both the Routing Over Low Power and Lossy Networks (roll) and IPv6 over the TSCH mode of IEEE 802.15.4e (6tisch) Working Groups on Thursday afternoon.
These are the IPv6 specific sessions in Yokohama, but IPv6 is has become such an integral part of the Internet that most working groups need to take it into account. At the Internet Society, we continue to promote IPv6 deployment. You can check out the World IPv6 Launch measurements for our latest measurements of IPv6 around the globe.
