16, 256, 65, 536, 16,777,216
Term
why do large organizations need to subnet their network?
Definition
performance issues: dividing networks into sub-networks isolates traffic flow into isolated groups of hosts. The Router creates different subnets. Placing the servers on separate subnets from host machines is common in larger networks.
Term
Do routers forward broadcast traffic? Explain
Definition
Routers do not forward broadcasts. Broadcast traffic remains within the subnet. An exception is DHCP server providing IP addresses to DHCP clients.
Term
