Hi Friends
I searched in the net but i could not understand what is
multicast Addressing
for eg consider the network having network Address 10.20.2.0 having
20 host
ranging from 10.20.2.1 to 10.20.2.20

my query is
1 . How to group the host in the Netwok Address who will do it
manually or by auto configuration
2. whether Macaddress will vary depending upon on the group,how the
system get it to know that it to accept the packet with these
MacAddress to be filled
3.How IP Address also vary

These may be idiot question for you...........
But if there is any one to give some idea means it is welcome ..and i
thankfull to them
Regards
