Dynamic DNS (DDNS) is a service to resolve a fixed domain name to a dynamic IP
address (such as ADSL dial-up Internet access) services. You need to apply to the DDNS
service provider for this service, and various service providers provide the specific service
of DDNS according to the actual situation. The DDNS service provider reserves the rights
to change, interrupt or terminate part or all of the network services. At present, the DDNS
service is free of charge, when the DDNS service provider may charge some fee for using
DDNS services in providing network services. In this case, HiPER Technology will give a
notice as soon as possible. If you refuse to pay such expenses, you cannot use the
related services. At the free stage, HiPER Technology does not guarantee the DDNS
service must be able to meet the requirements, nor guarantee the service will be
uninterrupted, nor guarantee the timeliness, safety, and accuracy of network services.
6.5.1 DDNS authentication
You can use the Ping command (for example: ping avery12345.3322.org) in the DOS
status of intranet computers, to check if the DDNS update is successful. Upon seeing the
correctly parsed-out IP address (for example: 58.246.187.126), it indicates that domain
name resolution is correct. Note: Under normal circumstances, the device's IP address will
not be pinged from the Internet after NAT is used on the device but only the IP address for
that domain name can be parsed out.
1. Only when the IP address assigned by ISP (Such as China Telecom) to the WAN port
connection line can the domain name be sure to be accessed by Internet users.
2. The DDNS function can help the Dynamic IP use VPN and server mapping.
