Part III: IP Addressing and Subnetting
Lab 4, “Finding the Subnet Number”–This lab shows how to find the subnet number in
which an IP address resides. It emphasizes the use of a process shown in the Cisco Press
Exam Certification Guides, a process which shows how to find the answers to subnetting
questions without using any binary math.
Lab 5, “Finding the Broadcast Address and Range of Addresses in a Subnet”–This lab
shows how to find a subnet’s broadcast address and the range of valid addresses in the subnet
given the subnet number. This video lab continues the same problem shown in ICND1 video
lab 4, again using a decimal-only process from the Cisco Press Exam Certification Guides.
Lab 6, “Finding All Subnets of a Network with Less than 8 Subnet Bits”–This lab shows
how to find all the subnet numbers of a single classful network, assuming a single subnet
mask is used throughout the classful network. This video emphasizes the use of yet another
decimal-only process shown in the Cisco Press Exam Certification Guides. This video uses
the same network and subnet mask used in labs 4 and 5.
Lab 7, “IP Subnet Design and Implementation”–This lab explains subnetting from a
design perspective, examining how to determine the number of required subnets and reviewing
how to find all subnets of a network using a particular static-length mask.
