Dynamic DNS
The Domain Name System (DNS) uses name servers to provide a mapping between computer-
readable IP addresses and human-readable hostnames. This allows users to access websites and
personal networks with easy-to-remember URLs. Unfortunately, IP addresses change frequently,
invalidating these mappings when they do. Dynamic DNS has become the standard method of
addressing this problem, allowing devices to update name servers with their new IP addresses.
By providing the IX20 device with the domain name and credentials obtained from a dynamic DNS
provider, the router can automatically update the remote nameserver whenever your WAN or public
IP address changes.
Your IX20 device supports a number of Dynamic DNS providers as well as the ability to provide a
custom provider that is not included on the list of providers.
Configure dynamic DNS
This section describes how to cofigure dynamic DNS on a IX20 device.
