N/A
3. Apply the DDNS policy to the
interface to update the mapping
between the specified FQDN and
the primary IP address of the
interface, and enable DDNS
update.
ddns apply policy policy-name
[ fqdn domain-name ]
By default, no DDNS policy is
applied to the interface, no
FQDN is specified for update,
and DDNS update is disabled.
If the DDNS service is provided by www.3322.org, the FQDN of the mapping to be updated must be
specified. Otherwise, DDNS update might fail.
If the DDNS server is a PeanutHull server and no FQDN is specified, the DDNS server updates all the
corresponding domain names of the DDNS client account. If an FQDN is specified, the DDNS server
updates only the mapping between the specified FQDN and the primary IP address.

Network requirements
• As shown in Figure 43, Router is a Web server with the domain name whatever.3322.org.
• Router acquires the IP address through DHCP. Through DDNS service provided by www.3322.org,
Router informs the DNS server of the latest mapping between its domain name and IP address.
• The IP address of the DNS server is 1.1.1.1. Router uses the DNS server to translate www.3322.org
into the corresponding IP address.
