Don't worry if your Internet becomes unresponsive on Wednesday[in Asia] - World IPv6 Day

 The world is changing, and with its rate of growth, we need more addresses for websites. And thus introduced IPv6, and its time the world gets adapted to it. June 8th, is considered as the World IPv6 day, a day when all prominent websites including, Gmail, Google, Facebook, Youtube etc will give their test on IPv6.
 Not aware of IPv6? Well, let me put in a short intro, we presently use IPv4 addressing, which is in the form of Its time that all combinations of this 32 Bit address exhaust. So IPv6 is introduced, with an address length of 128 bits, which is considered to never exhaust[Eg: 2001:0db8:85a3:0000:0000:8a2e:0370:7334]
 The Internet world have been prepping up for this day ever since, and now the day has come. Experts say the Users won't even know about the change into IPv6. The vast majority (99.95%) of people will be able to access services without interruption: either they’ll connect over IPv6, or their systems will successfully fall back to IPv4. However, as with any next-generation technology, there may be teething pains. Experts estimate that .05% of systems may fail to fall back to IPv4, so some people may find Google, Facebook, Yahoo, Bing and other participating websites slow or unresponsive on World IPv6 Day.
This is often due to misconfigured or misbehaving home networking equipment, such as home routers, that can make a computer think it has IPv6 connectivity when in fact it’s not working.
