6.1 SpeedTouch™ Dynamic DNS
Introduction Dynamic DNS is a mechanism, offered by several dynamic DNS service providers
(available through the Internet) that allows the mapping of a worldwide resolvable
static DNS host name to a dynamically (and temporarily) assigned public IP address
used for Internet connectivity.
This allows you to offer basic Internet services to the world wide web, through a
DNS host name, without the need for obtaining a static and worldwide unique
public IP address.
In most cases dynamic DNS service providers offer various host applications, which
run in background on a local computer and send IP address updates to a dynamic
DNS service server whenever the dynamically assigned public IP address has been
changed.
The SpeedTouch™ offers you an embedded dynamic DNS client, making the use of
third party host applications running on a local computer superfluous.
Applying for the
dynamic DNS service
Before you are able to use the SpeedTouch™ dynamic DNS client functionality, you
must first apply for a dynamic DNS account (and DNS host name) at one of the
available dynamic DNS service providers available on the Internet.
The SpeedTouch™ supports by default the following dynamic DNS service
providers:
DynDNS ( www.dyndns.org/services/dyndns/ )
StatDNS ( www.dyndns.org/services/statdns/ )
No-IP ( www.no-ip.com )
DtDNS ( www.dtdns.com )

Dynamic DNS client
configuration
The SpeedTouch™ dynamic DNS client service can be configured via the CLI or the
SpeedTouch™ Web Interface.
Below a short description on how to prepare your SpeedTouch™ for dynamic DNS,
using an imaginary account at the DynDNS dynamic DNS service provider using the
CLI interface.
Preparing the
SpeedTouch™ dynamic
DNS client
The procedure for enabling a dynamic DNS client consists of five steps:
1 Adding a dynamic DNS host name
2 Adding a dynamic DNS client
3 Modifying the dynamic DNS client
4 Refining the dynamic DNS service settings (optional)
5 Enabling the Dynamic DNS Service .
For more in-depth information on the CLI, see “2 SpeedTouch™ Command
Line Interface” on page 5 and the “SpeedTouch™ CLI Reference Guide”.
In a preliminary step, it is assumed that the SpeedTouch™ is already
correctly configured for your Internet subscription and connected to the
Internet, and that you have obtained a valid dynamic DNS account (and
DNS host name) at a dynamic DNS service provider (in this example
DynDNS).
