Term
| How to you find the broadcast address? |
|
Definition
| It is always the number right before the next subnet. For example for subnets 0, 64, 128, 192. For subnet 0 the broadcast is 63. |

|
Definition
| The numbers between, not including the first one and last one. |

Definition
how many subnets? 2^1=2
how many hosts per subnet? 2^7-2=126
What are the valid subnets? 256-128 = 0,128
broadcast address: 127 |

How many subnets: 2^1 = 2
how many hosts: 2^15 - 2 = 32,766
Valid subnets: 256-128 = 0 & 128 |
