DDNS configuration example with www.3322.org

Network requirements
As shown in
Switch acquires the IP address through DHCP. Through DDNS service provided by www.3322.org,
Switch informs the DNS server of the latest mapping between its domain name and IP address. Switch
uses the DNS server to translate www.3322.org into the corresponding IP address.
