This presentation compares IPv4 and IPv6. It begins with introductions of the group members and defines IP as an Internet Protocol address assigned to devices connected to a network. It then discusses the evolution of IP versions from IPv1 to the current IPv6. Key details provided include that IPv4 uses 32-bit addresses limiting its capacity while IPv6 uses 128-bit addresses allowing for vast expansion. The presentation outlines advantages and limitations of IPv4 and reasons for the development of IPv6, including the growing shortage of IPv4 addresses. It clarifies that IPv4 and IPv6 are not compatible but can co-exist on networks using dual stack technology.

3. What is IP?
An Internet Protocol address (IP address) is a numerical label assigned to each
device connected to a computer network that uses the Internet Protocol for
communication.
Functions :
An IP address serves two principal functions :
1.Host or network interface identification
2.Location addressing
3

4. IP versions : Journey from IPv1 to IPv6
1.Internet Protocol version 1-3 were not formally assigned
2.Internet Protocol version 4 (IPv4)
3.Internet Protocol version 5 (IPv5) was an experimental protocol in the 1980s
4.Internet Protocol version 6 (IPv6)

5. Introduction of IPv4 :
Internet Protocol version 4 is the fourth version of the Internet Protocol (IP)
which uses 32 bit .IPv4 allows 2^32 (4294967296 ) unique address .

6. IPv4 Classes :
Example : 117.162.41.42
192.168.30.20
Class Network Bits Host Bits Decimal Address
Range
Subnet Mask
Class A 8 bits 24 bits 1-126 255.0.0.0
Class B 16 bits 16 bits 128-191 255.255.0.0
Class C 24 bits 8 bits 192-223 255.255.255.0
Class D Reserved for
multicasting
Reserved for
multicasting
224-239 N/A
Class E Reserved Reserved 240-255 N/A

7. What are the advantages of IPv4?
1. Connectionless Protocol and Best effort
based
2.Widely supported
3.Support of all OS
4.Video libraries and conferences
5. Addresses are easier to remember

9. IPv6 :
● Next generation of IP address
● 128 bit Hexadecimal address
● Used both numbers & alphabets
● Example: 76DC ,34EF etc
9

10. Binary Conversion of IPv6
10

11. ● Able to support a huge increase in number of
users
11

12. ● Larger address space
○ Reachability
○ Scalability
● Almost unlimited number of IP address
● Network Architecture is very strong

14. Limitations of IPv4 :
IPv4 has been in use since 1978
- No substantial updates/improvements
Exhaustion of IPv4 address space
-Explosive growth of the commercial internet
Increase of IP-enabled devices
Integrated Security -
-Originally IPv4 -specification did not identify any security mechanism
IPsec was a later addition for IP
Scalability-Quality of service concern 14

15. Why no IPv5?
●Version 5 of the IP family was an
experimental Protocol
●Internet Stream Protocol
●Never introduced for public use
●Number 5 was already allocated,this
number was not considered for the
successor to IPv4

16. IPv4 and IPv6 are not cpmpatible :
1.IPv4 and IPv6 can not talk to each other
2.But they can exist together on the same network
3.Known as “Dual Stack”
-Computer has both an IPv4 and IPv6 address
-Uses one of the two when communicating
-If IPv6 is a available it usually has preferences
16

17. Why is IPv6 better than IPv4?
1.Larger Address Space
2.Better security for networks and applications
3.Better connectivity
4.Quality of service (QoS)
5.Data Integrity is improved
6.Better multicast routing
