Do you have an explicit listen-on directive in your named.conf?
Does named start more reliably if you have no listen-on directive, so that
it listens on all the interfaces that are available?
Named will use the routing socket to learn about interface
reconfiguration, so if systemd starts named before systemd has finished
bringing up the interfaces, named should be able to add the v6 sockets
when they appear (I hope).
Alternatively, maybe you could add something to the ExecStartPre in the
unit file to poll `ip addr show` until all the expected interface
addresses are present, so that named doesn't start until the rest of the
system has untangled its legs.
