DDNS stands for Dynamic Domain Name Service. If the AP+4
receives dynamic IP addresses from your Internet Service
Provider, the AP+4’s address changes whenever it connects to
your ISP. If you are running a Web server on your network,
clients will not know the AP+4’s IP address and will be unable to
connect.
However, you can use this page to sign up for a free trial
dynamic domain name service that will map changes in the IP
address to the Web server’s URL, so that network clients can
connect using that URL instead of an IP address. The client
