Dynamic DNS
The Domain Name System (DNS) uses name servers to provide a mapping between computer-
readable IPaddresses and human-readable hostnames. Thisallowsusers to access websites and
personal networkswith easy-to-remember URLs. Unfortunately, IPaddresses change frequently,
invalidating these mappings when they do. Dynamic DNShas becomethe standard method of
addressing this problem, allowing devices to update name servers with their new IPaddresses.
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
IPaddresschanges.
Your IX20 device supportsa number of Dynamic DNSproviders as well asthe ability to provide a
custom provider that is not included on the list of providers.
