The URL address for an update request can start with http://, https://, or oray://.
• http:// indicates the HTTP-based DDNS server.
• https:// indicates the HTTPS-based DDNS server.
• oray:// indicates the TCP-based PeanutHull server.
Applying the DDNS policy to an interface
After you apply the DDNS policy to an interface and specify the FQDN for update, the DDNS client
sends requests to the DDNS server to update the mapping between the domain name and the primary
IP address of the interface at the specified interval.
Configuration prerequisites
• Specify the primary IP address of the interface and make sure that the DDNS server and the
interface can reach each other.
• Configure static or dynamic domain name resolution to translate the domain name of the DDNS
server into the IPv4 address. For more information, see "Configuring static domain name
resolution."

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
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.
