6-2-4 DDNS Setting

The DDNS (Dynamic Domain Name Service) is used when users want to access NETCOMM
NS4540 with an easy memorized name such as http://demo.ddns.NetComm .com instead of
http://61.220.235.172. This service could be useful when NETCOMM NS4540 is located
behind a Dial-up ADSL or IP sharing device, which does not have fix IP address, then it's
impossible to reach NETCOMM NS4540 from Internet.

The mechanism of DDNS service is described as below:

When NETCOMM NS4540 enables the DDNS service, it will "register" to NETCOMM
DDNS server with its information, such as server name to access, router virtual port number
and updated frequency, etc.

Then NETCOMM NS4540 automatically "updates" to NETCOMM DDNS server by a fix
frequency, so even when an IP address is changed by the Internet Service Proivder (ISP), the
NETCOMM DDNS server still will obtain and update the internal database. Then, once users
access from Internet with its register name, e.g. if registering with server name "demo" to
DDNS server "ddns.NetComm .com", NETCOMM NS4540 can be accessed by http://
demo.ddns.NetComm .com.

Device Name: Specify server name. This name setting also used by NETCOMM DDNS
service to recognize each server.

Recipient: Your E-mail address.

Message subject: Subject of this E-mail.

e.g. if configure name as "company.user" to DDNS address "ddns.NetComm .com", then this
NETCOMM NS4540 can be accessed by URL http://company.user.ddns.NetComm .com after
registering the NETCOMM DDNS server.
