Network requirements
As shown in Figure 47, Router is a Web server with the domain name whatever.3322.org.
Router acquires the IP address through DHCP. Through DDNS service provided by www.3322.org
(www.pubyun.com), Router informs the DNS server of the latest mapping between its domain name and
IP address. Router uses the DNS server to translate www.3322.org (www.pubyun.com) into its IP
address.
