Creating a Subnet, Performing the AND Function And Subnetting Example

Creating a Subnet

•Determining subnet mask size

•Computing subnet mask and IP

address

•Computing hosts per sub-network

•Boolean AND operation

•IP configuration on a network diagram

•Host and subnet schemes

•Private addresses

Determining Subnet Mask Size

Class B address with 8 bits borrowed for the subnet

130.5.2.144 (8 bits borrowed for sub-netting) routes to

subnet 130.5.2.0 rather than just to network 130.5.0.0.

Determining Subnet Mask Size

Class C address 197.15.22.131 with a subnet

mask of 255.255.255.224 (3 bits borrowed)

The address 197.15.22.131 would be on the

subnet 197.15.22.128.
