A good description of multicast addresses and useful example code which can be used as the basis for any project using multicasting.

I think there have some clerical error about example in the article:
client source code and server source code should exchange there postion,
doesn't it?

It took 20 seconds to find that typo.
Please, check any code before posting it.

Your documents are very useful. I did not know anything about IGMP before reading your document. Could you correct me if the following are wrong.

Is the term IMGP proxy is the same as IMGP server ?

Is there such thing as IMGPv3 yet ?

Is that true that the main task for a IMGP server is to convert a ClassD client which registered in its pool into the MultCast Physical Addrees before data can be send out ?

Thank You
