3.3.7.4 DNS
DNS servers map the user-friendly domain names that users type into their Web browsers (e.g.,
"yahoo.com") to the equivalent numerical IP addresses that are used for Internet routing.
Configuring DNS Relay
When the device's LAN interface IP address is specified as the DNS address, then the ADSL/Ethernet
automatically performs DNS relay; i.e., because the device itself is not a DNS server, it forwards domain
name lookup requests that it receives from LAN computers to a DNS server at the ISP. It then relays the
DNS server's response to the PC.
3.3.7.5 DDNS
Dynamic DNS (DDNS) is a service that facilitates outside Internet access to a LAN host even when the
host's dynamically-assigned IP address changes frequently.
