Martin, for better or worse, there has been a trend in many
organizations to reflect the flatness at the top level with
flatness in subdomains. E.g., if the StupidAcme company had
departments for collections and customer abuse, their IT
department might set up a domain structure of
collections-hostA.StupidAcme.biz
collections-hostB.StupidAcme.biz
customer-abuse-hostA.StupidAcme.biz
customer-abuse-hostD.StupidAcme.biz
rather than
hostA.collections.StupidAcme.biz
hostB.collections.StupidAcme.biz
...
And that situation leads precisely to wildcard searches on zone
files or copies of them. Emacs is probably still the most
commonly-used tool for zone file editing and maintenance
worldwide.
This is arguably a really stupid way to use the DNS, but not one
that violates protocols or over which the IETF has any control.
