3. Introduction to IP Address
IP stands for Internet Protocol Address.
IP address is also known as “Logical Address”.
It is an numerical label to each devices exist in a computer network that uses internet protocol for communication.
It is described by Internet Engineering Task Force (IETF) in September 1981.
An IP address serves two principal functions : host or network interface.

4. Types of IP Addresses
Public
Private

5. Types of IP Address (Public)
A public IP address is any valid address, or number, that can be accessed over the Internet.
It is provided by ISP (Internet Service Provider)
We need to pay charges for this type of IP.
It is a globally unique on internet.
Two different hosts never have a same public IP address.

6. Types of IP Address (Private)
A private IP address is any number or address assigned to a device on a private TCP/IP Local Area Network that is accessible only within the Local Area Network.
This type of IP address provided by Network administrator to each host which exist in a whole.
This type of IP address unique within a network.
This types of IP can be repeated in a different local area network.

7. Types of IP Address (Private) Continued..
Ranges of Private IP address
First IP Address
Last IP Address

8. IPv4 and IPv6 IPv4 and IPv6 are the two versions of IP Address. IPv4
It is in form of Decimal No. 0-9
It is in form of Hexadecimal 0-9 & A-F
IPv4 are 32 – bit Length
IPv6 are 128 – bit length
It is separated by (.)
It is separated by (:)
It supports manual and dynamic configuration
It supports auto-configuration

9. Classes of IPv4 Address
IPv4 are divided into 5 classes that are listed below.
Class A – to
Class A supports 1,67,77,216 Addresses per network (2^24)
Class B – to
Class B support Addresses per network (2^16)
Class C – to
Class C supports 256 Addresses per network (2^8)
Class D – to
Class D for Multicast (i.e. One to Many)
Class E – to
Class E for Research & Development

8 bit bit bit + 8 bit = 32

11. IPv4 Subnet Mask
A subnet mask used to differentiate / separate host portion and network portion.
Following are the By Default subnet
A  ,67,77,216
B 
C 

12. IPv4 Subnet Mask (Continued..)
Network (N) and Host(H) Portion
N  1 and H  0
A   N.H.H.H
B   N.N.H.H
C   N.N.N.H .
Host portion defines no. of IP Address.

13. Conclusion
IP addresses and ports form the foundation for these Internet services. To help users, the Domain Name System assigns names to IP address.
