Witto's IP MultiCast Flood Predictor

Certain IP MultiCast addresses are guaranteed to flood your switched network regardless of the IGMP settings in your managed Switches

Note: If you have non-managed switches, all Multicast will be flooded anyway!!!

The MultiCast Flood Predictor provides a quick and convinient way to check that a particular IP address is :

  • Truely a Multicast
  • and Safe! (that is, will not produce a Link Local flooding)
and even determine the multicast MAC address

Use the Up and Down buttons to dial in your suspect IP address.

MultiCast Flood Predictor will confirm if the address is in fact MultiCast, and will check the corresponding MAC address for Link Local flooding.

The typical solution to avoid Link Local flooding, is to use an IP MultiCast address, where either of the 2nd and 3rd octets are NOT '0' or '128'

Additional information displayed is:

  • Multicast MAC address
  • Address in BINARY
  • Class of address ( A, B, C, D Multcast, or Reserved)
  • Public or Private IP address
