Sort of...
Strictly speaking, DNS is not required for internet access. More
accurately, an end user does not have to set up DNS on his/her machine
to enable him/her to go onto the internet. The internet service
providers provide one or more of their own DNS servers for the end user
to use.

Alternatively, it would be possible to use the /etc/hosts file to hold
the names and ip addresses of each machine on the internet, but this
would be totally impractical. DNS is used instead for this reason.
