I think he is using his own definition, not some witty
mathematico-grammatical repartee from someone I've never heard of. Let's
stick with John's clear and understandable definition and lose the
tortured prose of this Breidbart fellow.

You are a typical enterprise network. In other words, the situation that
you describe is rather common.

Then you are committed to a mental institution after overdosing on a
cocktail of drugs. Where else would you get the idea that spam and ddos
cause nuclear holocaust. This is a reductio ad absurdum if ever I saw

Not under the RFC 1918 definition.
