Assign IP address range

Specify the range you want to assign as addresses for multicast streams from the selected recording server. The clients connect to these addresses when the users view multicast video from the recording server.

For each multicast camera feed, the IP address and port combination must be unique (IPv4 example: 232.0.1.0:6000). You can either use one IP address and many ports, or many IP addresses and fewer ports. By default, the system suggests a single IP address and a range of 1000 ports, but you can change this as required.

IP addresses for multicasting must be within the range defined for dynamic host allocation by IANA. IANA is the authority overseeing global IP address allocation.

Name

Description

IP address

In the Start field, specify the first IP address in the required range. Then specify the last IP address in the range in the End field.

Port

In the Start field, specify the first port number in the required range. Then specify the last port number in the range in the End field.

Source IP address for all multicast streams

You can only multicast on one network interface card, so this field is relevant if your recording server has more than one network interface card or if it has a network interface card with more than one IP address.

To use the recording server's default interface, leave the value 0.0.0.0 (IPv4) or :: (IPv6) in the field. If you want to use another network interface card, or a different IP address on the same network interface card, specify the IP address of the required interface.

  • IPv4: 224.0.0.0 to 239.255.255.255.
  • IPv6, the range is described on the IANA website.
