Dear WG IPv6,

We are writing to share with the RIPE community our research work on IPv6 and we would appreciate having feedback from you.

If you find it useful, we are also available to present it at the next RIPE meeting in order to stimulate further discussion on this topic.

In this regard, we have presented a draft in IETF V6OPS WG (https://datatracker.ietf.org/doc/draft-vf-v6ops-ipv6-deployment/) and it should be discussed during the coming IETF 110.

In summary, the draft describes where the adoption of IPv6 stands in different domains (operators, enterprises, content providers, etc.), highlights possible steps to move the deployment of IPv6 forward, tries to stimulate the discussion on possible “calls for action” to further push the shift to IPv6, and presents some misconceptions as well as open points still to be faced related to that.

Some key findings of our work show that open aspects still remain, for which we would be happy to have the feedback of the RIPE community:

1. IPv4 exhaustion: the total remaining IPv4 address pool, as reported by the five RIRs at the end of 2020, has a bit more than 18 million addresses (either available or reserved). This data is summarized for example in https://www.potaroo.net/ispcol/2021-01/addr2020.html. However, from the same article, it appears that the pool of unadvertised addresses has grown in the past few years. Quoting it: “From 2018 to the end of 2020 this pool rose to around 50 /8s that were unadvertised in the public Internet”. On the one hand this seems a good sign for IPv6 deployment (e.g. IPv4 addresses are released). On the other, we may suspect that the IPv4 addresses are more than expected and that available space could be used, for example, for transfers. We would like to have your opinion on this.

2. IPv6 performance (latency, packet loss) seems, in some cases, worse than IPv4. Clearly, the perception of “bad” performance (relatively) might have a negative influence over the adoption of IPv6. What is the opinion of the community on this point?

3. IPv6 for Enterprises and Vertical Industry also shows a low level of deployment that can be investigated.

4. More could also be added.

We would be happy to discuss that with you. As said, we are also available to present our findings at the next RIPE meeting to bring it further.

Many thanks in advance

Paolo
