Appendix I. Practice for Chapter 18: Finding All Subnet IDs

This appendix lists two sets of problems. Both problem sets list an IP network and mask; your job is to list all the subnet IDs for each network/mask combination. The first problem set includes problems that happen to have eight or less subnet bits, and the second problem set includes problems that happen to have more than eight subnet bits. In particular, for each problem, find the following:

• All subnet numbers

• The subnet that is the zero subnet

• The subnet that is the broadcast subnet

To find this information, you can use processes explained in Chapter 18 of CCENT/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 18, “Finding All Subnet IDs,” in the same location where you found this PDF.)
