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

IPv6 Addressing for IPv4
IPv4-Compatible IPv6 Address format
IPv4-Mapped IPv6 Address format
0 IPv4 Address
96 Bits 32 Bits
0:0:0:0:0:0 192.168.10.10
IPv4 Compatible Address =0:0:0:0:0:0:192.168.10.10
= ::192.168.10.10
0 IPv4 Address
80 Bits 32 Bits
0:0:0:0:0:0 192.168.10.10
FFFF
16 Bits
IPv4-Mapped Address = 0:0:0:0:0:FFFF:192.168.10.10

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.

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

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
