*NOTE:
IGMP Proxy: works as an intermediate server; when it receives a query message from the
router; it sends a report message to the router port. When it receives a report message
from a device in a new group, it sends a report message back to the router port. When it
receives a leave message from a device which is the only one in the group, it sends a
leave message to the router port and removes the device. Proxy is like a middle man that
handles information in between routers and computers.
