IPv6Comprised of three words: •Internet •Protocol •Version 6
INTERNET •World wideinterconnection ofcomputer networks •For sharing and exchanging of information
PROTOCOLSpecial set of rules that enable communicationbetween computers(TCP/IP,HTTP,FTP)
INTERNET PROTOCOL •Method of datatransmission from one computer to another on the Internet. •Defines addressing system.
IP ADDRESSUnique address for •Identification •Addressing location
IP ADDRESSING 172.16.254.1 2001:db8:0:12 34:0:567:8:1
IP VERSIONS1.IP Version 4 (IPv4)2.IP Version 6 (IPv6)
IPv4 •Developed in 1970s •32-bit address•4294967296 i.e. (232) or 4 billion possible unique addressesThis is the version we all are currently using
IPV4Range of four decimal numbers is 0 to 255
IPv4 ADDRESS EXHAUSTION
NEED OF IPv6•To fulfill the demand of more IP addresses
IPv6 •Developed by InternetEngineering Task Force in 1995 •128-bits address-size340 billion billion billion billion or 2128or 3.403×1038 unique addresses
IPv6 ADDRESS NOTATION Group of 8 DECIMAL NUMBERS URL of the example:http://[2001:cdba:0000:0000:0000:0000:3257:9652]/2001:cdba:0000:0000:0000:0000:3257:9652
After IPv4 was IPv6 --why wasnt there ever a v5?
Top Features thatmake IPv6 greater than IPv4
#1) IPv6 provides a substantially larger IP address space than IPv4 CHALLENGE TO IPv4How does IPv6 provide a solution?
#2) IPv6 provides better end- to-end connectivity than IPv4CHALLENGE TO IPv4 How does IPv6 provide a solution?
#3)IPv6 has better ability for auto configuring devices than IPv4 CHALLENGE TO IPv4How does IPv6 provide a solution?
#4) IPv6 provides better security than IPv4 for applications and networks CHALLENGE TO IPv4How does IPv6 provide a solution?
#5) IPv6 gives better Quality of Service than IPv4 CHALLENGE TO IPv4How does IPv6 provide a solution?
#6) IPv6 offers better mobility features than IPv4 CHALLENGE TO IPv4How does IPv6 provide a solution?
#7) IPv6 follows the key design principles of IPv4, thereby permitting a smooth transition from IPv4.How does IPv6 provide a solution?
Advantages of Using IPv6 over IPv4 •Larger address space •Support for mobile devices •Simplified address auto-configuration •Improved address management •Built-in security with end-to end IP Sec •Enables more levels of hierarchy for route aggregation •Makes it possible to upgrade functionality as needed•On the IPv6 platform, billions of new devices even cars can be IPv6 enabled
