Hunh?

The Arpanet always used hostnames.  Just about the only time you
needed to specify a raw network address was when you were dialed into
a TAC and you did things like "@o 137" to connect to mit-mc.

DNS was created because the hosts.txt file, a single network-wide
file that listed the name, address, aliases, system type, etc., of
every host in the Arpanet got to be unmaintainable.

Routing is totally unrelated to DNS, based as it is in IP addresses.
Routers know nothing about DNS.
