# Apply the DDNS policy to interface Ethernet 1/1 to enable DDNS update and dynamically update the
mapping between whatever.gicp.cn and the primary IP address of Ethernet 1/1.
[Router] interface ethernet 1/1
[Router-Ethernet1/1] ddns apply policy oray.cn fqdn whatever.gicp.cn
After the preceding configuration is completed, Router notifies the DNS server of its new domain
name-to-IP address mapping through the PeanutHull server, whenever the IP address of Router changes.
Therefore, Router can always provide Web service at whatever.gicp.cn.
