When it looks up ns1.mymansions.com it notices that it resolves to the 
IP address of the host it's running on.

You apparently don't know what "zone" means in DNS; a zone is a portion 
of the DNS hierarchy that's managed as a single collection on a common 
set of servers.

Anyway, the way that servers discover that ns1.mymansions.com is the 
server that hosts those domains is via delegation records.  The .com 
server contains a record that looks like:

mymansions.com. IN NS ns1.mymansions.com.

and the .biz server contains:

mymansions.biz. IN NS ns1.mymansions.com.

and so on.
