FQDN

Specify the Full Qualified Domain Name (FQDN) in the IP-to-FQDN mapping for

update.

• 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

• 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.
