3. 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.

4. History of Computer Networks
ARPANET
• Communication
through
Computer came
into existence in
1969.

7. WHAT IS IPV6 ?
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)”.

8. Why Need IPV6 ?
• Deficiency of IPv4
• Address space exhaustion
• New types of service
 Security
 Mobility (MIPv6)
• Header and format limitations

9. Address Format
3FFE: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

10. IPV6 Addressing
128 bit Address Size
ퟐퟏퟐퟖ Address
More Than
“Three Hundred and Fourty Trillion, Trillion ”.
IPV4 ADDressing
32 bit Address Size
ퟐퟑퟐ Address
More than 4.3 Billion (4,294,967,296)

14. Benefits Of IPV6
 Expanded addressing capabilities
 Structured hierarchy to manage
• The Computer is an end
point in the network. It
sends and receives data.
routing table growth
 Serverless Auto-configuration and
reconfiguration
 Streamlined header format and
flow identification
 Improved support for options /
extensions

15. Features Of IPV6
Improved support for options / extensions
Mobility - More efficient and robust
mechanisms
Security - Built-in, strong IP-layer encryption
and authentication
Quality of Service
Privacy switch Extensions for Stateless Address
switch
Autoconfiguration (RFC 3041)

16. Issues of IPV6
Address length: usable addresses vs. overhead
Hop 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?
• It translates the
data produced by
the computer
into a form that
can be
transmitted over
the local
network.
--How is it best implemented?
DNS can be very important in the transition –
how?

17. CONCLUSION
 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
• Network media such
as cables or wireless
media provide the
means by which the
signals are
transmitted from one
networked device to
another
