> 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.
