Appendix H. Practice for Chapter 17: Analyzing Existing Subnets

Practice Problems

This appendix lists practice problems related to Chapter 17, “Analyzing Existing Subnets.” Each problem asks you to find a variety of information about the subnet in which an IP address resides. Each problem supplies an IP address and a subnet mask, from which you should find the following information:

• Subnet number

• Subnet broadcast address

• Range of valid IP addresses in this network

To find these facts, you can use any of the processes explained in Chapter 17 of the CENT/CCNA ICND1 640-822 Official Cert Guide. (If you are reading this as a PDF that came with CCNA ICND2 640-816 Official Cert Guide, you will find a copy of the ICND1 book’s Chapter 17, “Analyzing Existing Subnets,” in the same location where you found this PDF.)
