Thanks for the pointer.  In hindsight, I probably should have
recognized the similarity to the dangling CNAME problem while reading
that FAQ entry prior to posting.

Did that behavior change between MaraDNS and ?
I ask because the "dangling NS" issue does not present itself on my
old OpenWRT router running with a similar split DNS setup.

FWIW, since I already run dnsmasq in front of maradns, I chose to add:


entries in dnsmasq.conf rather than run a second instance of maradns.
The trade-off is now I have host data spread between two locations.

Perhaps a third, albeit more complicated, solution would have been to
do scheduled zone transfers from the upstream (public) DNS provider
and somehow merge the public addresses with the private IPs that
maradns is authoritative for using a script. 

Thanks for your help and for your work on MaraDNS, Sam.
