Dynamic DNS
Domain Name System (DNS) translates domain names
to IP addresses; Each DNS server on the Internet holds
these mappings in its respective DNS database. Dynamic
Domain Name System (DDNS) is a network service that
notifies the DNS server in real time of any changes in
the airFiber AF-5’s IP settings. Even if the airFiber AF-5’s
IP address changes, you can still access the airFiber AF-5
through its domain name.
Dynamic DNS If enabled, the airFiber AF-5 allows
communications with the DDNS server.
