Multicast traffic
Multicast traffic comes from one specific host (usually a server) and
goes to a multicasting group. In IP (Internet Protocol) valid groups
use the multicasting networking addresses (224.0.0.0 to
239.255.255.255) defined for IP. Management of group membership
and multicast traffic forwarding in switches and routers is done by the
IGMP (Internet Group Management Protocol).
Netmask
Tells how the IP-address is divided into the network portion and to the
host portion.
Network

resources. Two or more networks connected together is an internet.
Packet
A packet is the unit of data that is routed between an origin and a
destination on the Internet. When any file (e.g. an email message) is
sent from one place to another on the Internet, the file is divided into
packets of an efficient size for routing. When they have all arrived,
they are reassembled into the original file at the receiving end.
