Well I still don't really understand it but there was an arcane
setting on my Draytek router that was returning these incorrect
results. Quite how it was intercepting requests to specific DNS
servers out in the internet I don't quite know but I've simply
disabled and reset to factory default the settings in question and
everything looks a lot more sensible now! :-)

Sorry for the noise everyone.
