7.7.1 Introduction to DDNS
Dynamic Domain Name Service (DDNS) is a service used to map a domain name which never
changes to a dynamic IP address which can change quite often. For example, if you have
applied for a PPPoE connection with a dynamically DVVLJQHG,3DGGUHVVIURPWKH,63¶s PPPoE
server, you can use DDNS to allow the external hosts to access the Device by a constant
domain name.
In order to use DDNS service, you should apply for a DDNS account from a DDNS service
provider. Each DDNS provider offers its own specific network services. The DDNS service
provider reserves the right to change, suspend or terminate your use of some or all network
services at any time for any reason. The DDNS service providers supported by UTT
Technologies Co., Ltd. currently provide free DDNS services, but they may charge for the
DDNS services in the future. In this case, UTT Technologies Co., Ltd. will notify you as soon
as possible; if you refuse to pay for the services, you will no longer be able to use them. During
the free phase, UTT Technologies Co., Ltd. does not guarantee that the DDNS services can
meet your requirements and will be uninterrupted, and UTT does not guarantee the timeliness,
security and accuracy of the services.
So far, UTT Technologies Co., Ltd. only supports two DDNS service providers:
iplink.com.cn and 3322.org. It will successively support other DDNS service providers in
the future.
