Dynamic DNS
The NETA-21 provides support for the Dynamic domain name system (DDNS).
The Dynamic DNS service is useful when you have to access the NETA-21 with a dynamic
IP, for example, when the NETA-21 is located in an isolated region where the only network
access is through a 3G modem.

The toolbar of the Dynamic DNS tab contains the following buttons:
