NOTE:
•
At present, the DDNS update process does not have a unified standard and depends on the DDNS
server that the DDNS client contacts. The well-known DDNS service providers include www.3322.org,
www.oray.cn (also known as the PeanutHull server), and www.dyndns.com.
• 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.
Configuring DDNS
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 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 its IP address.
Configuration Procedure
Select Network > DNS > DDNS from the navigation tree to enter the DDNS page, as shown in
Figure 16 . Click Add to enter the page shown in Figure 17
