Retiring Test-Ipv6.com (retire.test-ipv6.com)

> I am shutting the site down, with a target of "during winter break" (December) 2025.

there is an engineer somewhere out there who will get paged on christmas due to a hidden dependency on this site being up, heh. that old xkcd comic comes to mind.

A big thank you to the creator. Was one of my goto sites to debug IPv6 issues on random devices over the years.

How much does it cost to run this sort of website? This one in particular has been a great help to me many times.

Thanks for the service. Showed that site to my own ISP's technicians when they were having difficulties to activate IPv6 support.

Unfortunately the reason is not because IPv6 is now globally available and IPv4 disappeared :(

Either way, a huge thank you from my side as well, this website has been (and still is) a very good troubleshooting tool to fix my IPv6 deployments

Tangential, but does anyone else struggle with their ISP implementing poor routing over IPv6 which results in packet loss? Mine does and I'm forced to use IPv4 which is behind CGNAT so that causes other issues but at least no lost packets.

The tier 2 support I've talked to has hot patched issues but then they re-surface a few weeks later.

If you are deploying a greenfield project in 2025 and you don’t bother setting up IPv6, you are failing. Also all internal virtual networks should by this point be IPv6 only or at least dual stack. The fact that we got unit testing to be the norm before IPv6 is negligent.

It was a great service over the past 1.5 decades.

I work with the engineer behind this (different team, but we interact semi-often and work on overlapping projects), but had no idea it was him until I looked at the little copyright notice in the footer. He is a fascinating guy and a fantastic engineer (one of those 10x engineers you hear about) while being humble and always willing to help out.

Thanks for the site for the last 15 years, it's helped me a number of times.

Ah, so I'll never be able to experience finally passing that test.. couldn't you wait like 50 years or something? My ISP needs some time..

Anyone have a good replacement if a different organization is not able to take over? This has always been my favorite IPv6 test site, and really appreciate the author maintaining it for so long.

It is absolutely amazing to me how far IPV4 + NAT have taken us.

Maybe the ISG would be interested in taking this over, possibly with some sponsorship money?

Oh this hurts a lot. I don't know of a good alternative to this website. Other sites I've found either run fewer tests (so are less useful for debugging) or incorrectly claim I don't have IPv6 (I do?).

I don't suppose we can donate some money to keep this website up? Or perhaps some company like CloudFlare would like to host a mirror?

Reach out to ben[1] from IPinfo, he took over ip4.me, ip6.me and a number of other websites following the passing of Kevin Loch earlier this year[2]. I am sure he would be happy to keep test-ipv6.com running without compromising it :) Very reputable, a great track record!

Thanks for the service. I used it to figure out what's wrong with my ISP's ipv6 and even though I never figured it out a fix your website definitely helped a lot.

Side note: I find ipv6 complex and very difficult to use. Might be because of the poor experience with my ISP, but still...

I definitely owe this guy a beer or coffee and hope to have a chance to make good on it.

Meanwhile Github still does not support IPv6

Please don’t turn it over to Cloudflare.

For anyone who is in need of a basic IPv6 test:

Naive question, but does this site actually require much ongoing maintenance?

I’ve used it for years and find it incredibly useful (& am appreciative of its existence) - just didn’t realize it needed much upkeep.

Could this site be run essentially free on Cloudflare using their managed transform headers features?
