Ch10 Subnetting Class 100326133817 Phpapp01

Module 10

10.3.1 Classes of network IP addresses

EG: An IP address 172.32.65.13 and a default subnet mask, the host belongs to the 172.32.0.0 network.

10.3.2 Introduction to and reason for subnetting

The benefits of Subnetting 1. smaller broadcast domains 2. low-level security provided 3. increased address flexibility

EG: In a class C network a subnet mask of 255.255.255.224 will create 6 useable subnets each with 32 useable hosts.

10.3.2 Introduction to and reason for subnetting

• •

Host bits of the network address are all equal to 0. Host bits of the broadcast address are all equal to 1.

Host bits are reassigned as network bits.

10.3.4 Applying the subnet mask

10.3.4 Applying the subnet mask

10.3.5 Subnetting Class A and B networks

16 bits are available for Class B host IP addresses using the default subnet mask.

Applying the subnet mask 255.255.255.0 to a Class B network will give 254 useable hosts and 254 useable subnets.
