Do I have static IPv6 addresses?

I currently have business class AT&T U-Verse service with five static IPv4 addresses. I'm working on some development sites for which it would be helpful to have static IP addresses, although I would need IPv6 addresses as I don't have enough IPv4 addresses to cover everything. Is there a block of static IPv6 addresses which comes with the U-Verse business class service and, if so, how do I access it, set it up in my router, and assign addresses?

Edit To Add: My gateway is a Pace PLC 5268AC. I use a MikroTik hAP-AC (cascaded from the Pace) as my LAN router.
