But doesn't that depend on how your switches are setup?. My understanding is the use of IGMP fixes this problem. The switch will only sent that multicast packets to switch ports which want it.

It really depends how relaible you need the data to be. Back in the days when everything went throug NZGate at Waikato they kept lists of NZ addresses based upon the BGP tables. These contain quite a few small blocks of non NZ addresses -- mainly belonging to large multination companies and Telcos. I imagine it has got worse not better. If accuracy is crucial then you really need something based on the routing tables that gets updated frequently. Russell
