Fixed ipv6 addressing

Hi , we have a business Fiber services and we need to have IPv6 static ip addresses, which is the procedure to get a fixed ipv6 block?, a /64would be ok.

To my knowledge, there is not a method to get a static block of IPv6 addresses on ATT service (maybe on their dedicated fiber service, but I wouldn't know for that).

I have service at 2 locations and the only time the /60 block assigned to the gateway has changed was when I went from VDSL to fiber, so it is a very sticky block.

Another option is to setup a IPv6 over IPv4 tunnel to someone like Hurricane Electric.  They provide static blocks, up to a /48 for free.  I used them about 4 or 5 years ago until ATT started blocking protocol 41.  If ATT is still blocking that protocol, you are out of luck for this option.  I was able to get the native service up and running, so I didn't really need it anymore.
