Wrong. DNS is not that simple.
Domains and sites have, in general, independent topology
that sites can not be responsible for domains.
Perhaps, your misunderstanding is commonly shared by those
who believe in NDN, though they might think there are
negligible number of exceptions.
Then, data, mostly, could be routed based on name hierarchy,
which scales well.
The reality, however, is that exceptions are everywhere
and we need something like DNS to translate names into
something scalably routable, that is, hierarchical
addresses.
