It’s not unheard of for an ISP to update customer firmware for v6 support in advance of deploying connectivity and addressing, with the result that the CPE offers ULAs internally even though there's no IPv6 provisioning in place, and 3484-style devices then having issues. Would be interesting as an aside to know the status of 3484 vs 6724 on various OSes, as well as those like OSX that appear to do their own thing.
