Item Description
Associated

Other
settings
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 may fail.
• If the DDNS server is a PeanutHull server and no FQDN is specified, the
DDNS server will update all the corresponding domain names of the DDNS
client account; if an FQDN is specified, the DDNS server will update only the
specified IP-to-FQDN mapping.
DDNS Configuration Example
Network requirements
• Device is a Web server with the domain name whatever.3322.org.
• Device acquires its IP address through DHCP. Through DDNS service provided by www.3322.org,
Device 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. Device uses the DNS server to translate www.3322.org
into the corresponding IP address.
