If with legacy web server you mean a dedicated server somewhere in a colo that has an IPv4 address, then yes. You can keep that until parts of the internet will no longer have any connection to IPv4 anymore.
If you expect to move that server, say to move to a new colo provider, do you get an IPv4 address there? If you have to pay extra each month for IPv4 and get IPv6 for free, do you pay?
Legacy desktops, there are these things like youtube, netflix, they eat huge amounts of bandwidth. As an ISP you don't want that through your carrier grade NAT boxes. Better try to get customers to use IPv6.
These days many web pages are insanely loaded with ads, trackers, etc. Lots of connections, again really bad for CGN.
Big CGN boxes are also really bad for geolocation. IPv6 is better for that.
There is also reason to believe that gaming behind carrier grade NAT is going to be pain.
Finally, if there was one group of products supporting IPv6 early on, it was operating systems. Even XP can do IPv6. Web browsers support IPv6 for a long time now. So as soon as the network provides IPv6, just about all desktops pick it up and start using it.
- pjc50 11y agoIf you want to serve web pages to most of the world, you have to have an IPv4 address, and that will continue until IPv6 adoption is well above 50%. Yes, there are places offering discounts for no-IPv4, such as lowendspirit. I have one. I have to bounce through another shell account to get to it as neither my home ISP nor workplace supports IPv6.
- kevcampb 11y agoAbove 50%? The threshold for not supporting IPv4 would be far higher than that. Think about how long it took to for companies to stop supporting IE6 when there was still only residual usage. The effect of not supporting IPv4 would be far worse as well - not just a buggy looking site, but zero functionality.
