False meme image that says “bad news ipv4 fans. linus torvalds has announced removing ipv4 support from the linux kernel after the maintainers of the network stack got into a fight over WHAT KIND OF HRT gives the best results. this incident will impact 5 billion people and will make 95% of all network equipment on Earth binnable.” with fake screenshots of the linux kernel mailing list a girl calling another one a slur from 4chan over HRT choices and Linus Torvalds saying he will drop IPv4 support and asking the maintainers to learn to shut the fuck up.
Yes, your ISP provides you a large quantity of adresses. Not really, the adresses has several parts. Your ISP provides you with the prefix. Your devices complete the rest of the address automatically. You can also use a DHCPv6 server, but I don’t and some devices don’t support it anyway. Yes, all those adresses are globally routable, they are “Internet” adresses. You can still use locally routable adresses too if you want, called Unique local address (look it up on Wikipedia), but that requires manual configuration.
I don’t think unique local addresses require manual configuration. On linux at least, I get an
fe80::
address derived from the interface’s MAC address even if there it can’t find any router. If the host receives a router advertisement, it will add a local address (the same suffix as the fe80 but with afd8b:something::/64)
and the “internet”2003::
.I’m not an expert and this may be just the configuration of my router, but all my linux installs automatically got these three addresses without manual configuration or issues.
That’s SLAAC not a ULA
