The Age of IPv6

The Age of IPv6


IPv6 - Internet Protocol Version 6 is the next generation protocol for the Internet. It's design for replace IPv6 .The primary reason for design IPv6 is because exhaustion of available IPv4 address Space.The IPv4 does not handle the address Space requirements of the ever-growing Internet.


Benefits of IPv6:

• Larger Address Space
• Simplified header format: Improves efficiency and new features
• Reduced management requirement
• Improved methods to change IPS
• Better Mobility Support
• Multi-Homing
• Embedded Security: Mandatory IPsec Implementation
• Scoped Address: link-local, site-local and global-address space

(Larger Address Space)
Compare to IPv4, IPv6 increase the number of address bits by a factor of 4. from 32 bits to 128 bits.


(Simplified Header Format)
The IPv6 had remove Identification, Flags, Fragment Offset,Header Checksum and Padding Fields. This result will speed up the processing of the basic IPv6.


(Embedded Security)
IPsec is mandatory in IPv6. IPsec is the Ip Security arhitecture that an protect all IP protocol communication

Scariest IPv6 attack scenarios.

Experts are reporting a rise in the number of attacks that take advantage of known vulnerabilities of IPv6, a next-generation addressing scheme that is being adopted across the Internet. IPv6 replaces the Internet's main communications protocol, which is known as IPv4.

IPv6: The security risks to business.

Predictions about when the world will end are about as consistent as the predictions about when IPv4 internet addresses will finally run out, but some IT security professionals say that is really the least of our worries.

A much bigger concern, they say, should be the security holes that will open up in many business organisations as the world moves over to internet protocol version six (IPv6).

Nothing either GOOD or BAD but thinking makes it so.

  When there is good there is also bad, What did you think about IPv6? The appear of Internet Protocol version 6 not definite as the End of the of Internet Protocol Version 4. 

IPv6 Does Not Mean the End of IPv4!
