NOTE
Dynamic DNS is a very useful tool for accessing a MxNVR-MO4 over the Internet, especially for xDSL
connections with a non-fixed IP address (DHCP). The administrator and users can simplify connecting to a
MxNVR-MO4 with a non-fixed IP address, by using the unique host name in the URL to establish a connection
with the MxNVR-MO4.
NOTE
Different DDNS service providers have different application rules. Some applications are free of charge, but
most require an application fee.
Universal PnP
UPnP (Universal Plug & Play)
is a networking architecture that provides compatibility among the
networking equipment, software, and peripherals of the 400+ vendors that are part of the Universal Plug and
Play Forum. This means that they are listed in the network devices table for the operating system (such as
Windows XP) supported by this function. Users can link to the MxNVR-MO4 directly by clicking on the
MxNVR-MO4 listed in the network devices table.

Multicast
The MxNVR-MO4 supports the advanced Multicast network protocol IGMP, which can greatly improve the
efficiency of network traffic. In this section, we explain multicasts, multicast filtering, and how multicast can be
implemented on your MxNVR-MO4.
What is Multicast?
A multicast is a packet that is intended for “one-to-many” and “many-to-many” communication. Users
explicitly request to participate in the communication by joining an end-station to a specific multicast group. If
the network is set up correctly, a multicast can only be sent to an end-station or a subset of end-stations on a
LAN or VLAN that belongs to the relevant multicast group. Multicast group members can be distributed across
multiple subnetworks. Therefore, multicast transmissions can occur within a campus LAN or over a WAN. In
addition, networks that support IP multicast send only one copy of the desired information across the network.
The packets are only replicated if they reach a network node that links to two or more members of the multicast
network. Transmitting packets in this way makes more efficient use of network bandwidth. A multicast packet
