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.
