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.
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
IPv4 Problems1) Random distribution of IP
Africa United States, Canada,
parts of theCaribbean
Asia PacificLatin America, parts of theCaribbean
Europe, Middle East, Central Asia
ISPs
IPv4 Problems2) Using NATUsing NAT to enable multiple hosts on a private network to access the internet using a single public IP
NAT Public IPAddress
IPv4 Problems3) Increasing the number of Users
The number of internet users increases continually , on the other hand the number of IPv4 addresses is constant
ICANN IPv4 Addresses
4.3 Billion IPv4 addresses are running out
Because all of this problems….
IPv6 has come
IPv6 features 1) The organized destribution of addresses
Africa United States, Canada,
parts of theCaribbean
Asia PacificLatin America, parts of theCaribbean
Europe, Middle East, Central Asia
ISPs
IPv6 features 2) Supporting more IP adresses
3) No need to use NAT anymore
