Don't your ISP offer static addresses as an option?

For a fee, yes. It's usually not cheap. Even "good" ISPs like Google Fiber basically make you upgrade to a "business" account , then buy static IP addressing as an add-on. It can end up costing twice as much as your regular residential service.

With IPv4 it has always made far more sense for hobbyists to just use a dynamic DNS service, of which there are many free options. Some registrars like Namecheap even offer it when you buy a domain. IPv6 obviously complicates the hell out of this and I haven't really seen a solution as easy as for your average hobbyist.

in uk many providers charge £5 for a static ip, some give static ipv4 for free

Why is it different? Can't you just dynamically update a AAAA record?

I've never done this, so asterisks as appropriate, but if you're using IPv6 to assign addresses from your block internally (that is, you aren't NATting your devices behind the router), you now have to invalidate all of them.

With IPv6, your ISP gives you a block of IP addresses which your router then divvies up among its clients. Each device on your network has a unique public IPv6 address, rather than sharing one and your router using NAT and port forwarding to direct traffic.

This makes dynamic DNS much more complicated because you can't just update the AAAA record with the address of your router, you need to update records for all clients that need to be externally accessible.

This is not an unsolvable problem, but it does make things a bit more complicated than just punching your DynDNS credentials into your router config or running Namecheap's DNS tool on one of your machines.

Yeah, Sonic walked back their promise to offer static IPv4 addresses with their fiber service (you can get one free static v4 address with their DSL offerings). They don't even do IPv6.

OTOH 10G fiber.

Telus won’t even do static addresses and IPv6. Either you get IPv6 or you can pay for static IPv4. You can’t even have static IPv4 and IPv6 enabled.

In the US, this is generally only available on "business" accounts. You can get a business account at your house but it will cost 2 to 3x for the same amount of bandwidth.

Not all of them do: after learning about that possibility here, I got myself an IPv4 subnet from AT&T fiber for no extra cost except the subnet itself
