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 Connect IT 4 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 Connect IT 4 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.
