Internet2 and the IPv6 Pod Project have been awarded $16k as part of the 2025 ARIN Community Grant program! Thanks to ARIN and ARIN community for making this possible!

For those of you who have applied for an IPv6 pod since the initial round of this project, thank you so much and I appreciate your patience. Over the next couple of months, we're going to procure hardware and get units out to people that we're able to serve (currently only in the US). We will provide updates as this project progresses.

For those interested in receiving a unit, our application form is a click away

HPN-SSH 18.7.1 has shipped this week with support for Happy Eyeballs, RFC 8305.

What is Happy Eyeballs?

Happy Eyeballs (RFC 8305) is an algorithm that improves network performance and reliability of dual-stack (IPv4/IPv6) clients by trying both IPv6 and IPv4 connections in parallel, but with a slight delay for the IPv4 attempt to favor the faster IPv6 connection.

What is HPN-SSH?

HPN-SSH is a version of OpenSSH developed for High Performance Computing uses in mind, namely faster transfer speeds, resuming of transfers, and other features not in the standard OpenSSH software. All while staying backwards-compatible with existing OpenSSH clients and servers.

How do I try it?

For those that want to try out Happy Eyeballs, upgrade to 18.7.1 and enable it by setting the config option HappyEyes to yes. Try it out and provide the HPN-SSH team some feedback. If all goes well, HappyEyes may default to being enabled in future releases.

ssh -oHappyEyes=yes me@my-server.org

The project is now accepting participation applications. Project participants will receive an IPv6 Test Pod at no cost. If you're interested in getting one, Fill out an Application!

Microsoft has announced that it plans to expand CLAT support to other interface types.

Microsoft's Announcemnt in the Tech Community forum:

... We are committing to expanding our CLAT support to include non-cellular network interfaces in a future version of Windows 11. This will include discovery using the relevant parts of RFC 7050 (ipv4only.arpa DNS query), RFC 8781 (PREF64 option in RAs), and RFC 8925 (DHCP Option 108) standards. Once we do have functionality available for you to test in Windows Insiders builds, we will let you know.

More information in the announcement post or IPv6 Buzz Episode 148.
