I don't agree with that.  Host names, and a means for translating
them to addresses, existed before DNS.  Introduction of hierarchical
naming and DNS let the maintenance of this translation mechanism be
decentralized.

Hm, wasn't this thread started by a suggestion that so-called
addresses be assigned under centralized control?
