Network Time Protocol (NTP) is a protocol for

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
device’s IP settings. Even if the device’s IP address changes,
you can still access the device through its domain name.

If enabled, the device allows
communications with the DDNS server.
