Configuring the Device as a DDNS Client

The device functions as the DDNS client. When the IP address corresponding to the domain name changes, the DDNS client can notify the DNS server to update the mapping between the domain name and the IP address on the DNS server. This ensures that users can successfully access servers on the network using domain names.

Pre-configuration Tasks

Before configuring a DDNS client, complete the following tasks:

  • Registering on the DDNS server website

    The device functioning as the DDNS client supports the following update modes:

    • DDNS update mode (defined by the RFC2136): The DDNS client dynamically updates the mapping between domain names and IP addresses on the DNS server.
    • Update mode implemented through the DDNS server: The DDNS client sends the mapping between domain names and IP addresses to the DDNS server with a specified URL. The DDNS server then informs the DNS server to dynamically update the mapping between domain names and IP addresses.

    When using the update mode implemented through the DDNS server, the DDNS client must register on the DDNS server website. Currently,the device can be connected to the following DDNS servers: DDNS serversprovided at www.3322.org, www.dyndns.org, www.oray.cn, and HTTP-based common DDNS server.

  • Configuring a route between the device and the DDNS server or DNS Server
