Unit 8 Lab 8

Lab 8.1: IP Addressing and Classes
Exercise 8.1.1
Network ID: 110 Host ID: 10.10.1
Network ID in binary: 1101110 Host ID in binary: 101010101
Exercise 8.1.2
Class
Range
Network ID
Host ID
Possible Networks
Possible Hosts per Network
A
0-127
A
b.c.d
2^7
2^24
B
128-191
a.b
c.d
2^14
2^16
C
192-223
a.b.c
D
2^21
2^8

If you used the number of bytes instead you would get a whole different amount of possible networks which isn’t right.
Exercise 8.1.3
No I will not fit in this the 192-223 range.
Exercise 8.1.4
Network ID: 190.8 Host ID: 8.4
Binary Network ID: 101111101000 Binary Host ID: 1000100
-This would be considered a class B

Exercise 8.1.5
255.255.255.0 = /24 11111111.11111111.11111111.00000000 total of 24 1’s
255.128.0.0 = /9 11111111.10000000.00000000.00000000 = /9 total of 9 1’s
Exercise 8.1.6
Block Size
Starting IP Address
Ending IP address
Subnet Mask (Slash Notation
24-bit block
10.0.0.0
10.255.255.255
255.0.0.0 = /8
20-bit block
172.16.0.0
172.31.255.255
255.255.0.0 = /16
16-bit block
192.168.0.0
192.168.255.255
255.255.255.0 = /24

Lab 8.1 Review
1. IP Address: 192.168.1.14 Subnet Mask: 255.255.255.0
The IP Address is Class C.
Its part of a the private block address
2. Using Subnet Mask addressing expands the capabilities while holding rules because of the wide variety of numbers that can be assigned. Not just IP address matters, now the Subnet Mask plays a part as well.

Lab 8.2: Assigning Static IP Addresses
Exercise 8.2.1
Does the ipconfig command still work?
Yes
Does the ping command still reach the default gateway?
No
Lab 8.2 Review
1. How does the practice of assigning static IP addresses on a home or small office network make troubleshooting problems on the network easier?
So that you can find the correct proper device when troubleshooting a particular issue. Also using a static IP can dial into the computer that is having any direct issues.
2. When would assigning static IP addresses be too
