> my ISP still gives me only a single IPv6 address

This is criminal, and also incredibly uncommon. You should talk to your ISP, it's most definitely a misconfiguration of some kind, if not deliberate torture. Normally you get a /56 at least because there are so many and they cost nothing.

Not at all. In China, where I live, this is often the case.

Many Huawei routers do it by default: they serve ULAs on LAN and do nat6 to a single public v6 address.

Is not "deliberate torture", it's just the easiest way to implement things

I've never seen this and I'm curious: do they actually pick a random /48 out of fd00::/8 like they're supposed to?

Datapoint of 1: With Cox as my ISP, I can get a /64 just by configuring my DHCPv6 client to request it, but if I wanted a /56 or /48 I would have to contact someone at my ISP.

I'm beginning to think it might be a US thing. Every time there's an ISP horror story, it's always the US.

There are exceptions, my ISP is Sonic and /56 prefix delegation works flawlessly with them.

Nah, we have the same thing in China.

Same at my place. I get a /64 prefix and my router simply cannot work with that at all.

What does IPv6 /56 cost if I would like to buy one for a server?

AWS will give you a "permanent" /56 for free in each region (in their address space, obviously)
