So where does DNS come in?  I think most DNS experts would define it as
a "distributed" system.  However there *is* a single entity that has
authority -- the root servers.  Compromise of that would compromise the
whole DNS system.  However there are watchdogs all over the world whose
role is preventing that.

I would argue that it's not a clear dichotomy between "shared" and
"distributed".
