With the DDNS client configured, a device can dynamically update the latest mapping between its
domain name and IP address on the DNS server through DDNS servers at www.3322.org or
www.oray.cn for example.
Configuration prerequisites
• Visit the website of a DDNS service provider, register an account, and apply for a domain name for
the DDNS client. When the DDNS client updates the mapping between the domain name and the
IP address through the DDNS server, the DDNS server checks whether the account information is
correct and whether the domain name to be updated belongs to the account.
• Specify the primary IP address and the security zone for the interface that is configured with DDNS
and make sure 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 an IP address.
Configuration procedure
1. From the navigation tree, select Network > DNS > DDNS.
The DDNS configuration page appears, as shown in
