NAT is the monstrosity, not IPv6.

But has the nice side-effect of working as a firewall, before traffic gets to you.

NAT has the side-effect of working as a shower curtain. It will mostly keep light drops of water out, but will not stand up to a fire.

When AWS rolled out plans to start charging for IPv4 addresses: https://aws.amazon.com/blogs/aws/new-aws-public-ipv4-address... "As you may know, IPv4 addresses are an increasingly scarce resource and the cost to acquire a single public IPv4 address has risen more than 300% over the past 5 years. This change reflects our own costs and is also intended to encourage you to be a bit more frugal with your use of public I…

What disgusted you about it? I'm out of the loop

They hadn't bothered to add ipv6 support to most of their services and the ones that did have it usually were only dual stack - still requiring an ipv4 address.

Really need governments to start pushing harder on IPv6 adoption. We need sticks, not just carrots. My favorite is chaos engineering forced IPv4 downtime.

Nah, we just need actual carrots. If something new is better than what people currently have, and you make it easy for them to get the new thing, people will naturally abandon the old thing. They'll do it happily. In fact, it will be hard to stop them from abandoning the old thing for the new thing.

IPv6 has failed at being better, being accessible, or both. Rather than punish people for failing to adopt something that isn't better or easy to get, either improve IPv6 so that it's actually attractive or admit defeat and start work on the next version that people will genuinely want.

The moment you start thinking "Let's make what people have now worse until they move to this other thing they don't want" its an admission that whatever you're pushing people to is shit.

The collapse in IPv4 transfer prices is what caught my eye here, dropping from a ~$55 peak in 2021 to a mean of $22 in early 2026 (figure 12). This validates my hypothesis that the run-up in 2020–2022 was an artificial scarcity bubble driven largely by hyperscalers. AWS was right up there stockpiling before they shifted their pricing model. Once AWS introduced the hourly charge for public IPv4 addresses (effectively…

As someone with a background in electronics who doesn't manage any internet-connected equipment but has multiple embedded devices connected to a WAN, I'm glad that IPv4 still seems to have a bit of life left in it. When IPv6 was developed, over 30 years ago, connecting everything to the internet seemed like a great idea. I know that IPv6 can be made secure, but I don't have the background or research time to learn ho…

IPv6 is just as secure as IPv4. NAT usually combines address translation with a stateful firewall. I remember when they were separate things. IPv6 has the stateful firewall, all the same security but without the mess of address translation.

Also, if you have devices connected to WAN, then they are insecure because they are not NATed.

In the US, I really want the FCC to mandate that an ISP provides IPv6 connectivity in order to meet the criteria to be considered broadband (and access the subsidies related to that). Don't even care if the functionality is off by default / you have to call and agree the routing may be sub-optimal, whatever. I currently use HE tunnels but on top of additional latency, the HE Cogent peering dispute still makes it diff…

There should be rule that ISP with CGNAT must offer IPv6 as an alternative. The US doesn't use CGNAT as much as other countries, but would help people stuck behind crappy CGNAT.

IPv6 routers use a stateful firewall just like NAT includes. Just without the problems of NAT.

I'm interested in any new successful startups going full IPV6 from the beginning. Once we cross that bridge, where your internal IPV4 knowledge is equivalent to token ring knowledge, there's nothing else to watch.

Github still refuses to switch on support for ipv6 traffic for some reason, so you can't interact with github then

The US government is pushing IPv6 for government sites and contractors.

I think there needs to be a push for IPv6-first networks for companies. ISPs in the US are pretty good about IPv6. But network engineers learned IPv4, and don't want to change what works, so companies lag behind. Changing existing networks is hard, but IPv6 is good candidate for new networks. This includes writing docs and eventually the education so IPv6 is the default.

There is no shortage. Go look at IPXO, you can sublease any block size. The RiR's should be reclaiming these unused addresses, but instead the ASN is allowed to sit on them or rent them out, regardless they're not being used. The shortage is caused by hoarding and RiR's not doing their job.

It would be a strange and unnecessary risk to take for a startup in my opinion.
