Greetings!
This isn’t a new problem but curiosity/frustration has now got the better of
me. I’ve a QNAP NAS box which registers itself under
‘waldorfdb.myqnapcloud.com’ with both IPv4 & IPv6 addresses.
My home lan router provides DHCP & DNS service courtesy dnsmasq. Sometimes my
local browser is unable to resolve the above domain name and the “Insecure DS
reply received” message is seen in the router’s syslog:

Curiously a few minutes later and all is well, or well enough that my client
gets an answer:

I only seem to see this behaviour if using Google's public DNS.
Anyone else seeing this sort of thing? Help! :-) I’m at your disposal.
Cheers,
