IPv4 and IPv6 addresses

Meaning of IPV4

192.210.145.112 IPv4 address 32bits (decimal form

divided into octets) 192.210.145.112/24 24 bit subnet mask

2001:CE8B:0011:0A00:8000:0000:ABCF:0001

IPv6 address 128 bits(hex form divided into 8 units, 16 bits ea.)

2001:CE8B:11:A00:8000::ABCF:1 compressed

2001:CE8B:11:A00::/64 64 bit prefix

What happened IPv5

new value

Internet Stream Protocal (ST) was created to transmit video,audio, and simulations over the Internet in 1979 and calledIPv5

Never really saw the light of day Operating on the same level as IP but using a different

header format than that used for IP datagrams.

How much IPv4 is left?( only 9% )

Limited organization

Require manually configure DHCP

Less secure

Another drawbacks

What if it takes longer?

IPv4 will live on No effect on existing infrastructure New infrastructure requires addresses

IPv4 address management Recovery of unused address space

A question of costs Cost of IPv4 vs cost of IPv6 deployment

Industry Market failure? Markets are oblivious to long-term risks whenshort term priorities override

IETF Technical community failure? Standards are mostly well developed

But they need running code

Governments Countries have failed? Individual countries can and do influence theirown industries and populace

What if it takes longer?

conclusion

No one has to be failed

All players need to work and act together

Technical standards, implementation byvendors, deployment by operators, use byusers

Best advice: sooner rather than later Start the planning process now

Why not IPV5 ?

Known as Internet ST (Stream Protocol)

packet looks very similar to its IPv4 sibling

Experimental protocol.Not in public use

Migration to IPV6

19/29

LCIT, Bhandu

Just one reason: More addresses

Billions Trillions Gazillions? Suffice to say, Enough for a long time

Plug and play

Consideration to real time

Simplification of the header format and reduction in size

Expanded addressing capability and auto configurationmechanism

Simpler, faster, cheaper network

Better for everyone

Other benefits of IPv6

Security benefits ofIPv6 Over IPv4

IPv4 - NAT breaks end-to-end network security

IPv6 - Huge address range No need of NAT

IPv4 IPSEC is OptionalIPv6 - Mandatory in v6

IPv4 - Security extension headers(AH,ESP)Back ported

IPv6 - Built-in Security extension headers

IPv4 - External Firewalls introduceperformance bottlenecks

IPv6 - Confidentiality and data integrity without need

for additional firewalls

Security Advantages ofIPv6 Over IPv4

IPv4 - Security issues related to ICMPV4.

IPv6 - ICMPV6 uses IPSEC authentication and encryptio

IPv4 - No mechanism for resistance to scanningIPv6 - RTS possible only in IPV6

IPV4 - Doesnt support Auto configuration

IPv6 - Built in Auto configuration support
