  1. CISCO Acadamic Instructor (CCAI) - Chapter 10: Layer 3 Routing and Addressing- Folien - Pilot-Lehrgang - Semester 1 17.07. - 28.07.2000

  2. Chapter 10: Layer 3 - Routing and Addressing 10.1 Network layers 10.2 Path determination 10.3 The purpose and operation of IP addresses within the IP header 10.4 IP address classes 10.5 Reserved address space 10.6 The basics of subnettings 10.7 Creating a subnet

  3. To create a subnet address, a network administrator borrows bits from the host field and designates them as the subnet field. The minimum number of bits that can be borrowed is 2. If you were to borrow only 1 bit, to create a subnet, then you would only have a network number - the .0 network - and the broadcast number - the .1 network. The maximum number of bits that can be borrowed can be any number that leaves at least 2 bits remaining, for the host number.In this example of a Class C IP Address, bits from the host field for the subnet field have been borrowed.

  4. Question: How many possible subnets are there with a 4 bit subnet field?
