8. Identify IP Class /Network

9. Identify Connectivity

10. Types of IP
Private IP
Private IP address is used to assign computers within your network without letting them directly expose to the Internet.
Public IP
A public IP address is an IP address that can be accessed over the Internet.
A public IP address is globally unique, and can only be assigned to an unique device

11. Private , Public IP Example

12. IP v-4 Structure/ Format
Consists of 32 Bit
IP Address consists of 4 Sections
Each Section is 8 Bit Long
Each Section can range from

27. Procedure for Subnetting
How many hosts you want per sub-networks
How many bits, you will use
What will be your new Subnet Mask
What will be Slash value
What will be block size / subnets
Total number of subnets
What will be the Network ID, Broadcast IP, First Useable
IP, Last Useable IP for each subnet

28. Procedure Host:50 How many hosts you want per sub-networks = 50
/ 24
Procedure Host:50
How many hosts you want per sub-networks = 50
How many bits, you will use
2n = 2*2*2*2*2*2 = 64
n=6
What will be your new Subnet Mask =
Slash Value : / 26
What will be block size / subnets = 64
Total number of subnets = 256 / 64 = 4

29. Block Size / Sub-Networks
Required Host:50
Block Size / Sub-Networks
Network ID
First Useable IP
Last Useable
Broadcast ID

30. Required Host:14 Network: 192.168.1.0 255.255.255.0
How many hosts you want per sub-networks = 14
How many bits, you will use
2n = 2*2*2*2 = 16
n=4
What will be your new Subnet Mask =
Slash Value = / 28
What will be block size / subnets = 16
Total number of subnets = 256 / 16 = 16

31. Block Size / Sub-Networks
Required Host:50
Block Size / Sub-Networks
Network Address

Required Host:950
How many hosts you want per sub-networks = 950
How many bits, you will use
2n = 2*2*2*2*2*2*2*2*2*2 = 1024
n=10
What will be your new Subnet Mask =
Slash Value : / 22
What will be block size / subnets = 4
Total number of subnets = 256 / 4 = 64
