IP address

  1. 1. IP ADDRESSING LUCKY CHAUHAN BCA ROLL NO: 26
  2. 2. WHAT IS AN IP ADDRESS? • “Internet protocol” • Unique no to an Internet connected • Links all internet activity back to the device/user
  3. 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. 4. TYPE OF IP ADDRESSES • Ipv4 • IPv6
  5. 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. 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. 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. 8. NAT CONTINUED…
  9. 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. 10. IPV6 EXAMPLE
  11. 11. DIFFERENT BETWEEN IPV6 AND IPV4
  12. 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. 13. TUNNELING / CONVERSION TOOLS • Toredo tunneling (IPv6-over-ipv4) • IPv6-over-ipv4 tunneling
  14. 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. 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. 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. 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. 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. 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. 20. CONCLUSION • IP addressing in essential • Helps to communicate between networks • Ipv4 • IPv6 • Tunneling • Protecting your IP address
