   That is correct. The DNS is just for mapping
names to IP addresses.

   I think it depends on how we define "working."
Packets can be delivered without the DNS. Hosts
can communicate even without the DNS. There
was an IPV4 network even before the DNS.
TCP/IP (regardless of version) works without
the DNS.

   The DNS just makes it more useful for
persons.
