Boolean Operations: AND, OR, and NOT

•AND is like multiplication.

•OR is like an addition.

•NOT changes 1 to 0, and 0 to 1.

Determining Subnet Mask Size 

 

Determining Subnet Mask Size

Class B address with 8 bits borrowed for the subnet

130.5.2.144 (8 bits borrowed for subnetting) 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)

11000101
