True dual-stack using DNS64? :) What DNS recursors do mobile handsets
use when both IPv4 and IPv6 PDP contexts do get established (or IPv4v6
for that matter)?

As far as I can see, properly supporting IPv6-only clients via
NAT64+DNS64 in the same... uhm... "network segment" is still an unsolved
problem. Still didn't find time (and motivation) to write up my approach
of using an EDNS "DNS64 desired" flag signalling. :)

Best regards,
