looking for practical info multicast

binarysoul

I know what multicasting is, but I don't know how to detect it on the network. Is there a particular port being used?

Can you please send your 'multicasting experience' my way

Not sure about port, but it will usually use the Class D range of IP's. It uses IGMP for group memberships and queries.

Bingo Netstudents!

IGMP is what I needed. I had seen this protocol, but never occured to me it could use IGMP.

Thanks for the hint! I will be all over it tomorrow.
