> After announcing its retirement, many generous people and organizations offered help - thank you! The project is now transitioning to an RIR (Regional Internet Registry), which will continue running the site in the public interest.

well played. threatening to turn it off on christmas was a great move, must've rattled a few cages in the industry lol.

Why would Christmas specifically be a date that would have this effect?

A lot of people are on vacation, so impact would most likely be larger compared to a normal day.

No one wants to get paged on christmas and find out that they have a dependency on an external service that was turned off for good.

It's an apparently-simple site, with a greater utility than might at first meet the eye. I've found it very useful over the years, and I'm glad Jason has found someone he's happy to hand it over to.

Thanks, Jason, all your efforts are much appreciated.

emphasis on "apparently simple"

icanhazip.com looks even simpler on the face of it but there's always shenanigans behind the curtain:

https://major.io/p/a-new-future-for-icanhazip/

Yes, I certainly don't intend anyone to read that I think it's actually simple.

aw, somebody owns icanha.zip but didn't point it at them.

I use it to test connectivity in general. That it also checks whether my IPv6 stacks works correctly is basically a bonus.

less useful but vaguely related

https://1.1.1.1/help

and even less usefull

https://ipv6test.google.com

https://cloudflare.com/cdn-cgi/trace also tells you your IP address (but not both), and is notable because it works on any site that cloudflare attacks

Meanwhile some ISPs are still not offering IPv6, such as Orange Belgium.

According to https://www.google.com/intl/en/ipv6/statistics.html, I think it's safe to say that the majority of ISPs are not offering IPv6, and some ISPs do offer IPv6.

My ISP publicly supports IPv6, but I've never gotten it to work properly, and none of the technical support I've been able to been forwarded to knows what's wrong either. Colleagues using the same ISP has the same problem, so doesn't seem to be an isolated incident.

I'm sure there are more people out there in the same situation.

If you look at the weekly profiles you'll notice that offices/companied are lagging behind private users. IT departments not willing to do anything. And IPv6 is used a lot on phones.

Telenet and Proximus do, so if you are in their service area, why not switch ? (Don’t know about Voo, I live in Brussels).

My mobile connectivity comes via Mobile Vikings which are now part of Proximus - also IPv6 there, and I love their excellent service.

For all of the bullshit that is Comcast and their ongoing mission to fully enshittify every single aspect of last-mile Internet delivery at the expense of consumers and taxpayers, I will say that at least they've had great IPv6 support for well over a decade at this point.

Yeah, I'm a Comcast customer and I'm very happy with their IPv6 support. The only things I would want different are a prefix larger than a /60 (say a /56), and the ability to have a permanently assigned prefix on my residential connection (but that's unlikely, I know). As evil as the Comcast business people are, their engineers clearly are trying to do right by customers.

Virgin Media in the UK are somewhat infamous for being non-committal about IPv6. There was a thread that ran for 13 years on their forums about it (locked in 2023): https://community.virginmedia.com/discussions/Setup/ipv6-sup...

Or Ziply Residential

They, as I, are waiting for ipv8. A simple addition of a 5th octlet, and a 6th for 'planet'.

Oh no, the Godwin's law equivalent for networking is proving itself once again.

>someone will again complain about the address format, without realizing that shoving in extra address bits on an IPv4 datagram is already a new protocol

So you are having all the pains of transitioning to a new Internet Protocol, but none of the benefits of having an actually huge address space.

https://news.ycombinator.com/item?id=39258290

No, it's very simple.

You set a bit, and if set it's routed using 6 octlets. If the bit isn't set, it's routed via 1.1.x.x.x.x.

Yes, legacy can only reach 1.1.x.x.x.x.

Done.

How is your proposal _materially_ different from today's NAT64 and the 64:ff9b::x.x.x.x prefix?

It doesn't include ipv6, and therefore ipv6's broken everything. It's just 100% ipv4 + two extra octlets.

Do you really think your solution of "IPv4 with extra octets" will not introduce so called "broken everything"...?

Whether it's the addition of one octet or twelve octets, you are nevertheless introducing a new Internet Protocol, and therefore you are going to face the reality of introducing a new Internet Protocol.

To think otherwise is delusional and is the reason why the "Godwin's law of networking" has become sort of a meme.

Not just ISPs github and npm still don't and AWS is iffy too.

I wonder which RIR it is. ARIN or RIPE?

Author seems to be based in the US, and IP address of the server is Linode/RIPE, so I'm placing a five eurocent bet on RIPE.

My guess would be RIPE, it would likely fit with the RIPE Atlas?

But it could also be APNIC, they put out a lot of observational reports too, so it could fit with my perception of them. Maybe LACNIC or AfriNIC wants to do something to raise their profile?

The cost of running this vs the benefit must be huge.

    > The project is now transitioning to an RIR (Regional Internet Registry)

RIR as in the orgs responsible for managing IP blocks? Huh?

What does that actually mean in the context of a website like this?

RIRs also run public (web) infrastructure, and it sounds like one of them will take over this project. What's your question exactly?

Ah yeah, I misread/misunderstood. I though they were saying they are transitioning INTO an RIR, as in becoming an RIR themselves.

Yes, but they run a bunch of other useful services for internet plumbers too.

This would just be another "general good of the internet" service.

RIPE for example run.

Atlas: A cooperative service for internet reachability and measurements. - https://www.ripe.net/analyse/internet-measurements/ripe-atla...

DNSMON: Monitor the root and TLD's and other key internet domains. Does so from many locations so as to test anycast issues. - https://dnsmon.ripe.net/

RIPEStat / BGplay: Debug and examine internet reachability issues. - https://stat.ripe.net/ - https://stat.ripe.net/bgplay

And volunteer resources to help to run other things, like https://www.as112.net/ that sinks all the PTR lookups for RFC1918 that leaks to the internet, among other things.

That a nonprofit entity whose mission it is to keep the Internet running smoothly decided to provide the resources needed to keep this useful service available.

That doesn't seem too surprising to me and should ensure that the site can be run sustainably without burning out volunteers.

Great!

Thanks!
