3.2.8 DDNS
DDNS allows you to map the static domain name to a dynamic IP address. You must get an
account, password and your static domain name from the DDNS service providers. For XRT-D,
you can assign a DDNS server for each WAN port. This router supports some DDNS service
providers, for example DynDNS and TZO.
