Question
Assume that you have been assigned 192.168.111.129/29.
How many bits are borrowed to create the subnet field? ________________
What is the maximum number of subnets that can be created with this number of bits? ________________
How many bits can be used to create the host space? ________________
What is the maximum number of host addresses available per subnet? ________________
What is the subnet mask, in binary and decimal format? ________________
Complete the following table and calculate the subnet that this address is on, and define all the other subnets (the range of host addresses on the subnet and the directed broadcast address on the subnet).
Answer the following:
What subnet is 192.168.111.129 on?
A junior network administrator is trying to assign 192.168.111.127 as a static IP address for a computer on the network but is getting an error message. Why?
Can 192.168.111.39 be assigned as an IP address?

Solution:
Assume that you have been assigned 192.168.111.129/29.
1. How many bits are borrowed to create the subnet field?
Solution: 3 bit are borrowed.
2. What is the maximum number of subnets that can be created with this number of bits?
Solution: borrowed bits = 3
total subnets = 2^3 = 8
3. How many bits can be used to create the host space?
Solution: 3 bits
4. What is the maximum number of possible IP addresses in the host space?
Solution: 2^3 = 8
5. What is the maximum number of IP addresses that can be actually assigned to a host device in a subnet?
Solution: 2^3 -2 = 8 -2 = 6
6. What is the subnet mask in binary representation?
Solution: 11111111.11111111.11111111.11110000
7. What is the subnet mask in decimal representation?
Solution: 255.255.255.240
9. What subnet is 192.168.111.49 on?
Solution: 192.168.111.48
10. Can a junior network administrator assign 192.168.111.31 as a static IP address for a computer on the network?
Solution: This IP does not fall under any subnet
11. Can 192.168.111.64 be assigned as an IP address to a subnet?
Solution: No
Subnet Number Subnet Address Range of IP addresses that can be assigned to a host device Direct broadcast address 1 192.168.111.0 192.168.111.1 - 192.168.111.14 192.168.111.15 2 192.168.111.16 192.168.111.17 - 192.168.111.30 192.168.111.31 3 192.168.111.32 192.168.111.33 - 192.168.111.46 192.168.111.47 4 192.168.111.48 192.168.111.49 - 192.168.111.62 192.168.111.63 5 192.168.111.64 192.168.111.65 - 192.168.111.88 192.168.111.89
