Re: [DNSOP] Terminology question: split DNS

I haven't been following the current thread but I have encountered this
topic before and I have thought about the implications for DNSSEC.

The terminology of "split DNS" -- and equivalently "split horizon DNS" --
is, in my opinion, a bit limited.  It's not too hard to imagine further
carve outs.  For me, the general case is at every point in the network,
there is an external world and an internal world.  Let's say I am in charge
of the systems that support a department within a division of a very large
company.  I could imagine a department DNS that resolves names within the
department but forwards other queries to the division DNS resolvers.  They
resolve names within the division and forward other queries to the
company's resolvers.  The company's resolvers handle queries for names
defined by the company and forward other queries to the outside.

If we're going to tackle this problem, let's do it cleanly and completely.
