Subnetting Speed Practice #4

As usual… you should practice subnetting regularly until you pass the ICND1, ICND2, and/or CCNA exams! Here’s some more practice. Also, you can answer the poll based on this week’s questions, last week’s, or any other week.

Suggestions BEFORE CLICKING to see the rest: be ready to start your timer. Be ready to finish all 5 problems.

Your job:  Based on an IP address/mask, identify:

1. List the number of network, subnet, and host bits
2. List the number of hosts addresses in the subnet
3. List the subnet ID, subnet broadcast address, and range of addresses in the subnet

Ready… steady… go!
