3.7 DNS & DDNS
When you have an Internet plan that provides a dynamic IP address, that is, an address which is dynamically assigned and
changes each time you connect, an easy way to provide a permanent address is to use a Dynamic DNS service. There are both
free and paid DDNS services available.
3.7.1 DNS & DDNS Configuration
Figure 181 – DNS & DDNS Configuration
3.7.1.1 DNS
The NTC-400 Series Router can operate as a DNS server for the connected local clients which get their LAN IPs from the
dynamic IP scheme. You can create a private host list for easy access to the hosts / servers in your intranet with
corresponding domain names.
3.7.1.2 Dynamic DNS
To host your server on a changing IP address, you must use a dynamic domain name service (DDNS). Therefore, anyone
wishing to reach your host only needs to know the domain name. Dynamic DNS maps the name of your host to your current
IP address, which changes each time you connect your Internet service provider.
The Dynamic DNS service allows the gateway to alias a public dynamic IP address to a static domain name, allowing the
gateway to be more easily accessed from anywhere on the Internet.
