I work with a small ISP running all Mikrotik routers. We deployed IPv6 a couple years ago to our customers with very few issues. We are configured with a IPv6 DHCP server running on each customer facing router and hand out a /56 prefix to each customer from a /48 pool on each router. We use RADIUS to authenticate the prefix to the customer and build the queue (based on customer router MAC). Our billing system gets the MAC via Option 82 on the IPv4 address and then uses that same MAC to authorize the IPv6 prefix.
This worked great until we started getting calls from Google router owners that were unable to get a prefix from us. After a couple of them called Google support to see why, we were told we MUST hand out a /128 address to the Google router along with the prefix.
While annoying, I'd still like to support those routers. Using a Mikrotik test router configured as a customer router, we check the "Address" and "Prefix" option in the DHCP client and it doesn't work. Checking just "Prefix" works fine but we are unable to get an address as well.
I have read through IPv6 documentation from Mikrotik on how to properly configure the IPv6 DHCP server to also create a address link along with a prefix and have not found any documentation on how to do this. I have plenty of prefixes I can set aside for /128 addressing to customers but don't see how to set this up to automatically happen when a DHCP client requests an address along with a prefix.
