Networking contd..
- Create a network which can help in connecting 2000 devices
- the host id size should connect to 2000 devices
- 2^n ~= 2000 answer would n is 11 as 2^11 = 2048
- Now host size would be 11 bits
- What should be ip addresss range? It is better to use private network cidr ranges
- Private cidr ranges
- 10.0.0.0/8
- 172.16.0.0/12
- 192.168.0.0/16
- Lets choose any one of the above ranges
iprange: 192.168.0.0/21
subnet mask: 11111111.11111111.11111000.00000000
255.255.248.0
- What would be ip address range for connecting to 3000 devices on your network?
2^n ~= 3000 n = 12
ip range: 172.16.0.0/20
subnet mask: 11111111.11111111.11110000.00000000
255.255.240.0
- What would be ip address range for connecting to 100000 devices on your network
2^n ~= 100000 n = 17
ip range: 10.0.0.0/15
subnet mask: 11111111.11111110.00000000.00000000
255.254.0.0
- Generally we would not work with one complete network, we try to break network into smaller sub networks and these smaller networks are called as subnets.
Networks and Subnets
- Lets try to create subnets from a network
network ip range: 192.168.0.0/16
subnet mask: 255.255.0.0
network id: 192.168
size = 65000
lets try to create a subnet which can connect to 200 devices
2^n ~= 200 n = 8
ip range: 192.168.0.0/24
subnet mask: 255.255.255.0
network id 192.168.0
size = 250
lets create two more subnets which can connect 200 devices each
192.168.00000001.00000000
subnet 2: 192.168.1.0/24
192.168.00000010.00000000
subnet 3: 192.168.2.0/24
- Lets try to create subnets from a network
network ip range: 10.10.0.0/16
subnet mask: 255.255.0.0
now lets create two subnets which can connect to 1000 devices
2^n ~= 1000 n = 10
ip address: 10.10.0.0/22
subnet mask = 11111111.11111111.11111100.00000000
= 255.255.252.0
ip address: 10.10.4.0/22
subnet mask = 11111111.11111111.11111100.00000000
- Lets create subnets (subnet1, subnet2) which can connect to 200 and 500 devices
ip address range: 172.16.0.0/16
subnet mask: 255.255.0.0
subnet1 : 172.16.0.0/24
2^n ~= 200 n = 8
subnet2:
2^n ~= 500 n = 9
172.16.0000001 0.00000000 => 172.16.2.0/23
255.255.254.0
- Try to calculate subnet cidr ranges for the office network shown below
