TAILIEUCHUNG - Lecture LAN connections: Constructing a Network addressing scheme

Networks, particularly large networks, are often divided into smaller subnetworks, or subnets. Subnets can improve network performance and control. A subnet address extends the network portion, and is created by borrowing bits from the original host portion and designating them as the subnet field,. | LAN Connections Constructing a Network Addressing Scheme Flat Topology Problems All devices share the same bandwidth. All devices share the same broadcast domain. It is difficult to apply a security policy. Lesson Aim Subnetworks Smaller networks are easier to manage. Overall traffic is reduced. You can more easily apply network security policies. Lesson Aim What a Subnet Mask Does Tells the router the number of bits to look at when routing Defines the number of bits that are significant Used as a measuring tool, not to hide anything Possible Subnets and Hosts for a Class C Network Possible Subnets and Hosts for a Class B Network Possible Subnets and Hosts for a Class A Network End System Subnet Mask Operation How Routers Use Subnet Masks Applying the Subnet Address Scheme Lesson Aim Octet Values of a Subnet Mask Subnet masks, like IP addresses, are represented in the dotted decimal format like .
