Therefore, Switch can always provide Web service at whatever.3322.org. DDNS configuration example with PeanutHull server Network requirements As shown in Figure 48, Switch is a Web server with domain name whatever.gicp.cn. Switch acquires the IP address through DHCP. Through the PeanutHull server, Switch informs the DNS server of the latest mapping between its domain name and IP address. The IP address of the DNS server is 1.1.1.1. Switch uses the DNS server to translate www.oray.cn into the corresponding IP address.
