Computer Networks
A Computer Network Is a collection of Computers and other hardware components interconnected by a communication channels that allow sharing of resources and information.
History of Computer Networks
ARPANET
• Communication through Computer came into existence in 1969.

WHAT IS IPV6 ?
IPV6—INTERNET PROTOCOLVERSION 6
IPV6 is the Internet's next-generation protocol, designed to replace the current Internet Protocol, IP Version 4.
Announcement Of IPV6 In WorldWide 14 July 1999 By “IETF(Internet Engineering Task Force)”.
Why Need IPV6 ?
• Deficiency of IPv4• Address space exhaustion• New types of service
Security Mobility (MIPv6)
• Header and format limitations
Address Format3FFE:085B:1F1F:0000:0000:0000:00A9:1234
8 groups of 16-bit hexadecimal numbers separated by “:”
Leading Zeros can be removed
3FFE:85B:1F1F::A9:1234
“::” All Zeros in one or more group of 16-bit hexadecimal numbers
IPV6 Addressing128 bit Address Size AddressMore Than “Three Hundred and Fourty Trillion, Trillion ”.
IPV4 ADDressing
32 bit Address Size AddressMore than 4.3 Billion (4,294,967,296)

Benefits Of IPV6
• The Computer is an end point in the network. It sends and receives data.
Expanded addressing capabilities
Structured hierarchy to manage routing table growth
Serverless Auto-configuration and reconfiguration
Streamlined header format and flow identification
Improved support for options / extensions
Features Of IPV6
switchswitch
Improved support for options / extensionsMobility - More efficient and robust mechanismsSecurity - Built-in, strong IP-layer encryption and authenticationQuality of ServicePrivacy Extensions for Stateless Address Autoconfiguration (RFC 3041)
Issues of IPV6
• It translates the data produced by the computer into a form that can be transmitted over the local network.
Address length: usable addresses vs. overheadHop limit: is 65K necessary?Max. Pkt. Size: Larger BW calls for larger pkts.Is the checksum necessary?How do servers handle both types of packets? Is security necessary in IP?
--How is it best implemented?DNS can be very important in the transition –
how?
CONCLUSION
• Network media such as cables or wireless media provide the means by which the signals are transmitted from one networked device to another
IPv6 is NEW …– built on the experiences learned from IPv4– new features– large address space– new efficient header– Auto-configuration
… and OLD– still IP– build on a solid base– started in 1995, a lot of implementations and tests done
