Look at me!!!

Know me!!!

Let’s Play!! IP Address: 192.168.1.10 Class: Binary Equivalent:

Let’s Play!! IP Address: 192.168.1.10 /24 Class: C Binary Equivalent:

Practice-Binary: Translate these addresses into binary: 213.45.37.123
What classes do they belong to?

Practice- Binary: Translate these addresses into binary:
: : : What classes do they belong to? C, C, A

Magic Number: In binary, which bit of the subnet mask (left to right) switches from 1’s to 0’s? Ex: /24: Now you try: /28

Magic Number: Now you try: /28 255.255.255.240

Magic Number: Why is this important?
/28 Subtract the value of that octet from 256. =240 = 16 Calculate the multiples of your magic number (16) from 0 up to 256 16 32 48 64…etc

*interesting octet is the octet in which the 1’s change to 0’s 144
Find the multiple of the magic number that is closest to but no greater than the IP address’s interesting octet value 160 16 176 32 192 48 208 64 224 80 240 96 112 128 *interesting octet is the octet in which the 1’s change to 0’s 144

*interesting octet is the octet in which the 1’s change to 0’s 144
Find the multiple of the magic number that is closest to but no greater than the IP address’s interesting octet value 160 16 176 32 192 48 208 64 224 80 240 96 112 128 *interesting octet is the octet in which the 1’s change to 0’s 144

Practice-Subnetting:
You have been given the IP address /24 You require at least 15 subnets. List: The required subnet mask The number of total subnets The number of available hosts per subnet The first four subnet addresses The valid range of host addresses for the first four subnets The Broadcast address for each subnet

Practice-Subnetting:
You have been given the IP address /24 You require at least 15 subnets. List: The required subnet mask: (/28) The number of total subnets: 16 The number of available hosts per subnet: 14 The first four subnet addresses: The valid range of host addresses for the first four subnets The Broadcast address for each subnet

You have been given the IP address 200. 100. 50
You have been given the IP address /24 You require at least 3 subnets. List: The required subnet mask The number of total subnets The number of available hosts per subnet The first four subnet addresses The valid range of host addresses for the first four subnets The Broadcast address for each subnet

The required subnet mask: /26: 255.255.255.192
You have been given the IP address /24 You require at least 3 subnets. List: The required subnet mask: /26: The number of total subnets: 4 The number of available hosts per subnet: 62 The first four subnet addresses: The valid range of host addresses for the first four subnets The Broadcast address for each subnet

You have been given the IP address 10. 1. 5
You have been given the IP address /29 You require at least 6 subnets. List: The required subnet mask The number of total subnets The number of available hosts per subnet The first four subnet addresses The valid range of host addresses for the first four subnets The Broadcast address for each subnet

You have been given the IP address 10. 1. 5
You have been given the IP address /21 You require at least 6 subnets. What subnet mask should you use? You have a host at the address of that is experiencing issues. In order to troubleshoot, what is the address of that subnet?

What subnet mask should you use?
You have been given the IP address /21 You require at least 6 subnets. What subnet mask should you use? /21: You have a host at the address of that is experiencing issues. In order to troubleshoot, what is the address of that subnet?

/26 You need to have no more than 25 hosts in each subnet. Go.

Subnets: Ranges: Broadcast: 10.5.10.192 10.5.10.224 10.5.10.193 – 222
