Written Labs 3

In this section, you'll complete the following labs to make sure you have the information and concepts contained within them fully dialed in:

• Lab 3.1: Written Subnet Practice #1
• Lab 3.2: Written Subnet Practice #2
• Lab 3.3: Written Subnet Practice #3

(The answers to the written labs can be found in Appendix A.)

Written Lab 3.1: Written Subnet Practice #1

Write the subnet, broadcast address, and valid host range for question 1 through question 6 and then answer the questions that follow:

1. 192.168.100.25/30
2. 192.168.100.37/28
3. 192.168.100.66/27
4. 192.168.100.17/29
5. 192.168.100.99/26
6. 192.168.100.99/25
7. You have a Class B network and need 29 subnets. What is your mask?
8. What is the broadcast address of 192.168.192.10/29?
9. How many hosts are available with a Class C /29 mask?
10. What is the subnet for host ID 10.16.3.65/23?
11. What form of NAT maps multiple private IP addresses to a single registered IP address by using different ports?
12. What does the term inside global address represent in the configuration of NAT?
13. What diagnostic tool will you use to test a remote host's IP stack?
14. What diagnostic tool will you use to display IP-to-MAC addressing on a Windows PC?
15. What is the IP address range for subnet 192.168.2.64/26?
16. How many hosts does the subnet 172.16.112.0/20 provide?
17. What is the subnet address of 172.16.159.159/22?
18. What is the subnet for the host ID of 10.16.3.65/23?
19. What is the broadcast address the host 10.16.3.65/23 will use?
20. Two routers are connected with a serial connection. One is configured with IP address 192.168.10.82/30, and the other is 192.168.10.85/30. Why won't the two routers communicate?

Written Lab 3.2: Written Subnet Practice #2

Given a Class B network and the net bits identified (CIDR), complete the following table to identify the subnet mask and the number of host addresses possible for each mask:
