Associated
Interface
Select an interface to which the DDNS policy is applied.
The IP address in the host name-to-IP address mapping for update is the primary
IP address of the interface.
IMPORTANT:
You can apply at most two DDNS policies to one interface, and at most six to a host
through DHCP.
FQDN
Specify the FQDN in the IP-to-FQDN mapping for update.
The FQDN is the only identification of a node in the network. An FQDN consists
of a local host name and a parent domain name and can be translated into an
IP address.
• If the DDNS service is provided by www.3322.org, the FQDN 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 specified
IP-to-FQDN mapping.
DDNS configuration example
Network requirements
Firewall is a Web server with the domain name whatever.3322.org.
Firewall acquires its IP address through DHCP. Through DDNS service provided by www.3322.org,
Firewall 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. Firewall uses the DNS server to translate www.3322.org into
the corresponding IP address.
