multicasting and should be in the range 224.0.0.0 to 239.255.255.255 for IPv4 or have 
the prefix ff00::/8. An address in the range 239.252.0.0 to 239.255.255.255 is 
recommended.

Configuring Registration Settings 
Automatic Registration allows the device to automatically register to the proxy you have 
specified. This allows you to use the client-end to access the NVR through the proxy, where 
the proxy has a switch function. In the network service, the device supports the server address 
of the IPv4. 
1.  Go to Main Menu  Setting  NETWORK  Register. 
2.  Configure the proxy Host IP address, port, and sub-device ID at the device end. 
 
Note 
The proxy server generates a serial number for the sub-device 
ID.
