This guide provides step-by-step instructions on setting up DNS for system and/or LAN.

Overview

DDNS can be used by users whose ISP (Internet Service Provider) is providing a dynamic IP address for their service.  This type of connection is frequently used in residential internet connections.  Using an internet connection with a dynamic IP address can make accessing the ZLD appliance from a remote location (the internet) a challenging task.  This is because the IP address can change at any time.  The IP address for a dynamic internet connection may change if the router/modem is rebooted, or, when the DHCP lease expires.  This means the user must constantly verify the internet IP address and memorize the string.  This can become a cumbersome task.  Setting up DDNS allows the user to create a hostname with a supported DDNS provider, the ZLD device can then update this hostname with the correct IP address.  With DDNS accessing the ZLD device from a remote location becomes easier since there is no longer an IP address that needs to be verified and memorized.
