ROLL NO: 26

2. WHAT IS AN IP ADDRESS?
• “Internet protocol”
• Unique no to an Internet connected
• Links all internet activity back to the device/user

3. WHY DO WE NEED AN IP ADDRESS?
• Uniquely identifies your device in a network
• Send information from one network to another
• Security reasons

4. TYPE OF IP ADDRESSES
• Ipv4
• IPv6

5. HOW IS A IPV4 ADDRESS GENERATED?
• 32-bit numbers
• Using binary
• Decimal system
• Divided into four 8-bit values
• First part identifies the network
• Last part identifies the device in the network
• Supports up to 4.7 billion addresses

6. HOW MANY PEOPLES USE INTERNET ENABLE
DEVICES?
• About 7 million peoples
• 63.1% of population uses internet
• Each person by have many devices
• Ipv4 supports 4,294,967,296 addresses
There are not
enough
addresses!!!!!

7. USING NAT
• deficit of ipv4 address
• Limited IP addresses
• NAT(that work address translation) is used
• Translate the address of all devices in a private network
• Convert into one single public address
• Returns back to private network into its original IP address

8. NAT CONTINUED…

9. IPV6
• 128-bit address
• Using binary
• Hexadecimal system (0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,andf)
• Divided into parts of 4
• Supports up to 304,
282,366,920,938,463,463,374,607,431,768,211,456 Devices

10. IPV6 EXAMPLE

11. DIFFERENT BETWEEN IPV6 AND
IPV4

12. IP USAGE
• IPv6 was deployed in 2012
• Not every device use IPv6
• Ipv4 and IPv6 are not compatible
• Must be converted to one another

13. TUNNELING / CONVERSION TOOLS
• Toredo tunneling (IPv6-over-ipv4)
• IPv6-over-ipv4 tunneling

14. TOREDO TUNNELING
• Solve the problem of trying to use an IPv6 host
• Sending message through the requirement of ipv4 address
• Also solve the problem of getting int NAT Routers
• Use a platform in dendent tunneling protocol
• Encapsulates IPv6 data packet within the ipv4 data protocol

15. TUNNELING CONTINUED…
• Meant to be “temporary”
• As more device transition into IPv6
• IPv6 uses continues to grow
• Ipv4 and NAT have began to reach their limits

16. DANGERS WITH IP ADDRESS
• Using IP track someone can get your personal info
• Can locate you geographically
• You can be ddos’d
• All device are not protected
• Heavy cannot with another Person who has an IP tracking
software is all it take to get a hold of your IP address

17. PROTECTING YOUR IP ADDRESS
• Using VPN
• Proxy server
• Direct tracking software to another IP address/location
• Prevent tracking of your location and giving your personal
information

18. VPN
• Virtual private network
• Masks your IP as if it where a private network when in a public
network
• Allows remote user and office to securely access corporate
applications
• Can access secure information safely

19. PROXY SERVER
• Redirects the IP address location to another parts of the world
• Using a proxy server in Laredo,tx mite se you are in Russia
• Some sides block unsecure IP addresses
• Useful for keeping your location safe when tracking

20. CONCLUSION
• IP addressing in essential
• Helps to communicate between networks
• Ipv4
• IPv6
• Tunneling
• Protecting your IP address
