Hello,
With DDNS, which associates a static domain name with the dynamic IP address of its host, users on the Internet can access the server only with domain names.
1. In most cases, the default user name for logging in to the web page is root, the password is admin, and the IP address is 192.168.100.1. However, for security reasons, the default password or IP address may have been changed before delivery. The nameplate prevails. Enter the IP address in the address bar of your browser.
2. Enter the default login account and password on the nameplate on the rear of the ONT, and click Login.
3. Click the Network Application tab and then choose DDNS Configuration from the navigation tree. In the right pane, configure DDNS parameters, including Service Provider, Host Name, Service Port, Domain Name, Username, and Password.
4. Click Apply.
Dynamic domain name service (DDNS) associates a static domain name with the dynamic IP address of its host.
Assume that server A provides HTTP or FTP service and it is connected to the Internet using routers. If server A obtains an IP address through DHCP, or server A is connected to the Internet through PPPoE, PPTP, or L2TP, the IP address is a dynamic IP address. That is, its IP address may change each time when server A initializes its connection to the Internet.
The mapping between the domain name and IP address provided by the domain name service (DNS) server is static, and the mapping does not update when the IP address changes. Therefore, when the IP address of server A changes, users on the Internet cannot access server A with domain names.
Thanks
