A Domain Name System (DNS) server runs special-purpose networking software, features a public IP address, and contains a database of network names and addresses for other Internet hosts.It also communicate with each other using private network protocols. All DNS servers are organized in a hierarchy. At the top level of the hierarchy, so-called root servers store the complete database of Internet domain names and their corresponding IP addresses.
This document explains the procedure to add a DNS Server address manually on the RVL200 VPN Routers.

Step 1. Use the Router Configuration Utility to choose Setup > Network. The Network page opens.
Step 2. Check Use the Following DNS Server Addresses box to manually add the DNS server address.
