why IPv6 isn't ready for prime time

Apropos nothing, I tried to bring up IPv6 with another service
provider today (this being the fourth I've attempted with only one
success) but all I'm getting is:

%BGP-3-NOTIFICATION: sent to neighbor xxxx:xxxx:1000:A000::6 2/7
(unsupported/disjoint capability) 0 bytes

:frowning:
