Subnetting
- A subnet is a logical segment of larger network & subnetting is a logical addressing technique that creates smaller subnets using existing IPV4 addreses
- Subnetting
- Scenario: An organization has created a network for private usage Refer Here the organizational network cidr range is 10.10.0.0/16
- Now we are asked to create two subnets which can hold 500 devices
subnet size should be ~= 500 2^n ~=500 n => 9 SM=> 11111111.11111111.11111110.00000000 N/W Range => 10.10.0.0./16 subnet1 =>10.10.0.0/23
- Scenario 2: An Organization has a private network of range 172.16.0.0/16. We need to create 3 lab networks and each lab has 2000 devices
hosts => 2000
2^n ~= 2000
n=11
172.16.00000xxx.xxxxxxxx => 172.16.0.0/21
172.16.00001xxx.xxxxxxxx => 172.16.8.0/21
172.16.00010xxx.xxxxxxxx => 172.16.16.0/21
- Scenario 3: In your home you are create 3 smaller networks your network range for home 192.168.0.0/24. You need to create 3 subnets which can connect to 30 devices
number of devices = 30
2^n = 30
n =5
192.168.0.000xxxxx => 192.168.0.0/27
192.168.0.001xxxxx => 192.168.0.32/27
192.168.0.010xxxxx => 192.168.0.64/27
