This seems like an evergreen content topic. It's obvious that IPv6 adoption is high enough and critical for some industries in particular (i.e. cellular providers) with lots of endpoints. Increasing endpoint adoption is good. But service providers need to care about the remaining percentage. Say you get to 80, 90, even 99% adoption. An SP still can't flip IPv4 off. So what does it matter? It really doesn't warrant much concern.
- simoncion 8mo ago> So what does it matter? Yeah. There's a type of person who's obsessed with "cleanliness". For such a person, the goal is to have exactly one protocol on The Internet. Such a person would lose their goddamn minds if they had to actually work as a WAN administrator or datacenter operator. One of IPv6's purposes is to reduce pressure on the IPv4 address space. I don't expect IPv4 to get deactivated within the lifetime of any current HN reader; there's really no point in doing so. I expect the future for noncommercial sites to be "globally-routable IPv6 service, and IPv4 service by way of a CGN", which is how things are set up today in some parts of the world. IPv6 will be the default, with v4 as a fallback for folks need to talk with others who can't be bothered to update their software or kit.
- patmorgan23 8mo agoWhen you get to high 90s adoption you can start to run v4 as an overlay on a V6 native network. That's what the big US mobile carriers do, when they use 464XLAT, the edges get v4, but it all gets tunneled/translated to v6 in the middle.
