You don't have to worry about that, the printer won't use it. You can get your DNS server settings from any computer by running the "ipconfig /all" command if you want to enter it. DNS is what translates IP names to readable human names like www.google.com When you enter that, a DNS server looks up that name, looks up what IP address it has and then sends the data to that IP address. Computers don't talk to each other by name, only by the network port address.
