DDNS
Dynamic DNS is a service that provides you with a valid, unchanging, internet
domain name (an URL) to go with that (possibly ever changing) IP-address.
The DDNS (Dynamic DNS) service allows you to alias a dynamic IP address to a
static hostname, allowing your computer to be more easily accessed from various
locations on the Internet.
Without DDNS, the users should use the WAN IP to reach internal server. It is
inconvenient for the users if this IP is dynamic. With DDNS supported, you apply a
DNS name for your server (e.g., Web server) from a DDNS server. The outside users
can always access the web server using the www.ata.com regardless of the WAN IP.
When you want your internal server to be accessed by using DNS name rather than
using the dynamic IP address, you can use the DDNS service. The DDNS server
allows to alias a dynamic IP address to a static hostname.
Unlike DNS that only works with static IP addresses, DDNS works with dynamic IP
addresses, such as those assigned by an ISP or other DHCP server. DDNS is popular
with home networkers, who typically receive dynamic, frequently-changing IP
addresses from their service provider.
DDNS is a method of keeping a domain name linked to a changing (dynamic) IP
address. With most Cable and DSL connections, you are assigned a dynamic IP
address and that address is used only for the duration of that specific connection.
With the SATSPEEDBOX III R7920, you can setup your DDNS service and the device
will automatically update your DDNS server every time it receives a different IP
address.

DDNS Server Type: Support three types of DDNS, DynDns.org or TZO.net or
No-IP.
