1. Subnet 68.0.0.0 255.0.0.0 so that there are at least 1,700 subnets.

Bits borrowed = 14
New subnet mask = 255.255.192.0
Increments = 64
First 3 assignable ranges = 68.0.64.1 - 68.0.127.255,
68.0.128.1- 68.0.191.255, 68.0.192.1- 68.0.255.255

2. Subnet 150.216.0.0 255.255.0.0 so that there are at least 200 hosts per subnet.

Bits borrowed = 8
New subnet mask = 255.255.255.0
Increments = 128
First 3 assignable ranges = 150.216.128.0 - 150.216.255.255
150.217.128.0 - 150.217.255.255
150.218.128.0 - 150.128.255.255

3. Subnet 172.16.0.0 255.255.0.0 so that there are only 2 usable hosts per subnet.

Bits borrowed = 12
New subnet mask = 255.255.240.0
Increments = 16
First 3 assignable ranges = 172.16.16.0 - 172.16.31.255
172.16.32.0 172.16.47.255
172.16.48.0 172.16.63.255

4. Subnet 200.200.200.0 255.255.255.0 so that there are 10 subnets.

Bits borrowed = 4
New subnet mask = 255.255.255.240
Increments = 16
First 3 assignable ranges = 200.200.200.16 200.200.200.31
200.200.200.32 200.200.200.47
200.200.200.48 200.200.200.63


5. Another way to write a subnet mask, instead of in dotted decimal notation, is to write it in slash (/) format. Ex: 255.255.255.0 would be /24. In the slash format, the number after the / indicates the number of bits set to 1 in the subnet mask. Since 255.255.255.0 has 24 bits set to 1, it is /24.

What would the slash format be for the following subnet masks?
a. 255.0.0.0 /8
b. 255.255.0.0 /16
c. 255.192.0.0 /16
d. 255.255.248.0 /24


6. What layer of the TCP/IP model do IP addresses reside?
The network layer?

7. Since IP is specific to the TCP/IP model, and the OSI model does not specify any particular protocol, what would an IP address be considered in the OSI model?
a. Physical Address
b. Logical Address
c. Port Address
d. Application Address

8. In problem #3, there are only 2 usable hosts per subnet. In what situation would only two hosts exists on a subnet? Explain your answer in 1 paragraph or more.

This sounds like home work?
