OK, David, thanks for that. I think that my confusion is arisng because
the times when I have used DNS servers before they always talked to an
upstream server (like NTP systems do), as they were providing address
information for a sub-domain. In that case, it was a bi-directional
Thie idea of configuring my own DNS server to talk directly to the root
DNS servers for the Internet had not occured to me, just as one would not
normally talk to a stratum one NTP server directly. [Is there anything to
learn from this for the NTP guys?]. I understand from what you say that
this root contact will only be once for each root domain (e.g. .uk), thus
alleviating the load. So I would never (under normal circumstances) need
to add the address of any upstream server at all. Understood.
I've added the .invalid at the end of my address (although while writing
this post rather than before writing, so it may not appear) to alleviate
any excess load I may be causing.
