IP Setup > DDNS Configuration
The DDNS Client is used to update the IP address of the modem/router in a DDNS server for the configured domain
name whenever the IP Address changes, thus, leaving the domain name to be pointing to the current IP Address of the
modem/router all the time.
General
DDNS: Check the Enable or Disable box to indicate whether or not you want a DDNS Client.
Default = Disable.
User Check IP: Check the Enable or Disable box. If enabled, the program will query the server to
determine the IP address before it performs the DDNS update (the IP address is still assigned
by the wireless provider and the DDNS will be updated based on the address returned by
Check IP Server). If disabled, the program will perform the DDNS update using the IP address
that it obtains from the PPP link.
