The built-in DHCP Server function is NOT always configurable and is greatly dependant to the
connection type that is set to "Device Network Setting":
1. If the connection type is "Auto Mode", the DHCP server function is NOT configurable. It will
be ON if the NVR doesn't obtain an IP from a DHCP server in the local network and uses its own
default static IP 192.168.101.50
2. If the connection type is "Auto Mode", the DHCP server function is NOT configurable. It will
be OFF if the NVR obtains an IP from a DHCP server in the local network.
3. If the connection type is "DHCP Client", the DHCP server function is NOT configurable. It will
be OFF if the NVR obtains an IP from a DHCP server in the local network.
4. If the connection type is "DHCP Client", the DHCP server function is NOT configurable. It will
be ON if the NVR doesn't obtain an IP from a DHCP server in the local network and uses its own
default static IP 192.168.101.50
5. If the connection type is "Static IP", the DHCP server function is configurable and can be
turned on/off manually.

7.1.3 DDNS Service

DDNS, which stands for "Dynamic DNS", is a method, protocol, or network service that provides
the capability for a networked device, such as a router or computer system (in this case, the
NVR) using the Internet Protocol Suite, to notify a domain name server to change, in real time,
the active DNS configuration of its configured host names, addresses or other information
stored in DNS.
A popular application of dynamic DNS is to provide a residential user's Internet gateway that
has a variable, often changing, IP address with a well-known host name resolvable through
standard DNS queries.
This is useful if the NVR is placed on the Internet with a dynamic public IP, which once the
DDNS is properly set up, users can access the NVR remotely with the DDNS domain name
without worrying if the IP has changed or not.
