Conﬁguring DDNS

8 Conﬁguring DDNS

Dynamic DNS (DDNS) is a service that allows computers to use the

same domain name, even when the IP address changes from time

to time (during reboot or when the ISPʼs DHCP server resets IP

leases). RX3042H connects to a DDNS service provider whenever

the WAN IP address changes. It supports setting up the web

services such as Web server, FTP server using a domain name

instead of the IP address. DDNS supports the DDNS clients with

the following features:

• Update DNS records (addition) when an external interface

comes up

• Force DNS update

HTTP DDNS Client

HTTP DDNS client uses the mechanism provided by the popular

DDNS service providers for updating the DNS records dynamically.

In this case, the service provider updates DNS records in the DNS.

RX3042H uses HTTP to trigger this update. RX3042H supports

HTTP DDNS update with the following service provider:

• www.dyndns.org

Figure 8.1. Network Diagram for HTTP DDNS

Whenever IP address of the conﬁgured DDNS interface changes,

DDNS update is sent to the specified DDNS service provider.

RX3042H should be configured with the DDNS username and

password that are obtained from your DDNS service provider.
