  1. 1. Main Points : What is IP? IPv4 IPv4 Problems IPv6 features Syntax of IPv6 Types of IPv6 addresses Migration IPv6 with IPv4
  2. 2. What is IP ? • An Internet Protocol (IP) address is a numerical identification (logical address) that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes.
  3. 3. IPv4• IPv4 uses 32-bit (4-byte) addresses, which limits the address space to 4,294,967,296 = (2^32) possible unique addresses . Ex: 192.168.1.1
  4. 4. IPv4 Problems 1) Random distribution of IP Africa Latin America, Europe, Asia Pacific United States, parts of the Middle East, Canada, Caribbean Central Asia parts of the Caribbean ISPs
  5. 5. IPv4 Problems 2) Using NAT Using NAT to enable multiple hosts on a private network to access the internet using a single public IP NAT Public IP Address
  6. 6. IPv4 Problems 3) Increasing the number of Users The number of internet users increases continually , on the other hand the number of IPv4 addresses is constant4.3 Billion IPv4 addresses are running out
  7. 7. Because all of this problems….
  8. 8. IPv6 features 1) The organized destribution of addresses Africa Latin America, Europe, Asia Pacific United States, parts of the Middle East, Canada, Caribbean Central Asia parts of the Caribbean ISPs
  9. 9. IPv6 features 2) Supporting more IP adresses 3) No need to use NAT anymore
  10. 10. IPv6 Syntax Eamples:-2001:0050:0000:0000:0000:0AB4:1E2B:98AA 2001:0050::0AB4:1E2B:98AA 2001:50::AB4:1E2B:98AA
  11. 11. Types of IPv6 addresses 1) Global unicast address 2) Link local address Start with FE80
  12. 12. Migration IPv6 with IPv4 1) NAT 2) Dual stack 3)Tunneling
