Preparing the SpeedTouch™ dynamic DNS client

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.

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)

GnuDIP

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.

For more in-depth information on the CLI, see “2 SpeedTouch™ Command Line Interface” on page 5 and the “SpeedTouch™ CLI Reference Guide”.

The procedure for enabling a dynamic DNS client consists of five steps:

1Adding a dynamic DNS host name

2Adding a dynamic DNS client

3Modifying the dynamic DNS client

4Refining the dynamic DNS service settings (optional)

5Enabling the Dynamic DNS Service.

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).
