DNS is short for Domain Name System. It is a network functionality that allows
network members to use host names rather than IP addresses for referencing
networked computers.
The DNS web page consists of two sections:
Configuration
Hostname Table
In addition to the host name, a local computer needs the DNS domain name to
construct a fully qualified name. By default the SpeedTouch™ DNS's domain name is
lan. You can specify another (sub)domain name in the domain field (and Apply)
In normal conditions you should never disable the SpeedTouch™ DNS server, surely
not in case the SpeedTouch™ DHCP server is active on the local network as well. If
required however, you can disable the SpeedTouch™ DNS server by clearing Activate
Server (and Apply).
Disabling the SpeedTouch™ DNS server will disable all DNS forwarding
functionality as well. This may compromise end-to-end connectivity through
the SpeedTouch™ connections.
The Hostname Table shows all DNS host names (with respective IP address) the
SpeedTouch™ DNS server is aware of (for example entries created via DHCP server
replies to leases).
If not all computers reveal their hostname in the DHCP request, or even worse if they
do not support DHCP, static entries can be added to the local DNS database.
Proceed as follows:

In the Hostname field, type the name you want to associate to the specified IP
