   * **Optimized bandwidth utilization**:  IGMP snooping reduces flooding of packets.  The device selectively forwards IPv4 multicast data to a list of ports that **want** to receive the data instead of flooding it to all ports in a VLAN.
   * **Improved security**:  Prevents denial of service attacks from unknown sources.

+===== When to Enable IGMP Snooping for Home Use =====
+Enable IGMP when you frequently use any kind of streaming or mirroring from your devices to stream to IOT devices, such as Chromecast or Apple TV.
+Do not turn it on unless actually needed.  This will just add extra traffic, which the router will need to listen to and monitor; and could result in less performance.
