Cloud and IPv6 Workshop

This workshop of the UK IPv6 Council gave information about the current level of IPv6 support in various Cloud offerings, as well as other IPv6 challenges in virtualised environments.

It was held at Imperial College London on Tuesday 3rd September 2019, from 1.00pm to 5.30pm.

The rationale: Existing information on the Internet is piecemeal, hard to put together for Cloud customers and therefore we want to enable our members and the industry with this information.


13:00 – 13:30 – Doors open – buffet lunch will be available

16:45 – 17:15 – Overview of IPv6 support in container technologies (Pieter Lewyllie, Cisco, BE) (PDF)
17:15 – 17:30 – Closing & relocation to a nearby pub

As we usually do, we will go for a few drinks after the event where everyone is welcomed to join us and continue discussing IPv6 in a less formal setting. The pub to meet in is The Queen’s Arms, which is at 30 Queens Gate Mews, Kensington, SW7 5QL.
