But would this "home" DNS server provide records accessible to others?
If in fact it is straightforward surely it must be set out 
explicitly somewhere?

Incidentally, I do already check every 15 minutes if the IP address
of the dynamic-address server has changed - it changes every few days -
and if it has the remote server sends me email.
