World IPv6 Day is June 8th, 2011. It serves as a test of IPv6 functionality on the internet.
Numerous large content providers, equipment manufacturers and ISPs participate, such as Answers.com, Google, Facebook, Yahoo, Juniper, Cisco and Akamai. These organizations, and many others like them offer their services over IPv6 in addition to IPv4 for a 24-hour period beginning at 00:00 UTC and ending at 23:59 UTC.
This test-flight is intended to motivate organizations to move forward with their plans to deploy IPv6 and ease the migration off of IPv4 in preparation for the impending IPv4 address space exhaustion. It is also designed to help elucidate current IPv6 readiness across the Internet, and possibly uncover existing problems.
Two other similar events have taken place in the past, on September 16, 2010 and October 26, 2010, on a much smaller scale.
There is no ipv5, just as there are no ipv1, ipv2, and ipv3. Most networks in the world use ipv4 with a few having upgraded to ipv6.
what is the commercial use of ipv6?
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
Short answer - yes.You need to be running Service Pack 1 at a minimum.Service Pack 2 has an even more complete IPv6 stack.To enable IPv6 on XP, open a command prompt window and type:C:\> ipv6 /?Did you then see this result?:C:\> ipv6 /?Could not access IPv6 protocol stack - the stack is not installed.To install, please use 'ipv6 install'.If you did get the above result, simply type:C:\> ipv6 installIt will take a few seconds, and then your Windows XP system will be fully IPv6 enabled.
IPV6 is relatively new and doesn't work everywhere yet.
IPv6 uses a 128-bit address space
IN IPv6 we can find 128bits.
IPv6 address has 2^128 address and IPv6 address is of 16 bytes and is represented in colon hex notation.
by unchecking the check box of IPv6 in local area network properties
By configuring an IPv6 Unicast routing command on a router you are allowing the router to communicate with the IPv6 interface. This is needed if you intend to send or receive data over an IPv6 network.
there are exactly340,282,366,920,938,463,463,374,607,431,768,211,456 ip address in the next generation internet protocol knows as IPv6 for more info visit: IPv6.com
Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​ smb
