Note: DNS (Domain Name System) is for mapping a domain name to its corresponding IP
address and vice versa. The DNS server is extremely important because without it, you
must know the IP address of a computer before you can access it. The Zyxel Device
uses a system DNS server (in the order you specify here) to resolve domain names for
VPN, DDNS and the time server.
