      Okay, so this is *really* stupid. On NTT FLET's, if you don't have a Hikari Denwa contract, you only get a /64 prefix assigned via IPv6 RA. If you do, you get a /56 via DHCPv6-PD. The /56 I just got? It's *the same as my old /64*. They are allocating a /56 for everyone anyway

      So why the hell isn't the delegation available for everyone instead of this ridiculous "you have to sign up for a VoIP contract to get more than one IPv6 subnet" nonsense?

      Do you pay someone more money to sign up for a VoIP contract to get your /56?

      Yes, ¥500/mo more. At least the VoIP contract will be useful because I get near-zero coverage in half of my apartment...

      Well there you go. Can't expect crapitalists not to impose arbitrary restrictions to increase their profits. Totally absurd of course but unless we can convince our politicians to outlaw profiteering for the sake of it then this is the sad world we live in :(

      Given that this is Japan and NTT, it's way less likely that this is profit-driven and exceedingly more likely that it's just something completely dumb, like, say, that their VoIP routers can't pass through a /64 cleanly or that they decided to implement this for that service.

      Like, there's probably 5 of us signing up for VoIP just to get a /56. They aren't making a fortune off of this policy.

      That might explain why there isn't just an arbitrary fee for a /56 without VoIP though. Correct me if I'm wrong here (and I'm sure you will :P) but can't VoIP just be run over normal internet like any other protocol? Does it need special handling?

      Yes, it's just a server on their network available both via the normal IPv6 routing, and via a dedicated DHCP/IPv4 feed to a private net you get when you have the service (I think some of their gateways use v4 and some v6?). Normal IPv4 internet is either PPPoE or DS-Lite.

          All this stuff is complicated enough (and hidden behind Japanese routers built for it for normal people) that I'm pretty sure there is some (no doubt dumb) technical/bureaucratic reason for this.
