Is this the end of Internet and IPv4 the next Disaster?????


Now a day’s have you ever been without surfing Net a day??? The answer is No.

Internet has become an essential part of our lives. Everybody is on the Net, surfing with different types of devices including PC’s, Laptop, iPads, and Mobile phones. Each of these need a unique IP address on internet, when directly connected. The present Internet Protocol (IP) addressing system-IPv4-uses a 32 bit number, represented in 4 octets, for example 192.158.21.30

The problem with IPv4 is that IPv4 addresses are 32-bit numbers, there are only 2^32, or just over four billion possible addresses available; and they have all been allocated. On Feb 3, 2011, the Internet Assigned Numbers Authority (IANA), which controls the worldwide distribution of IP addresses, allocated the final pool of IPv4 address space to five Regional Internet Registries (RIRs). This means that there are no longer any IPv4 addresses available for allocation from IANA to the five RIRs.

So does this mean the end of the Net?????????

Well, not really. The new addressing scheme, IPv6, uses 128-bit numbers for addresses. Hence, there are 2^128individual addresses available. All new IP addresses from now will be IPv6. But the main problem here is that IPv4 is not directly compatible with IPv6. This means that devices connected via IPv4 cannot communicate directly with systems connected using IPv6, and vice versa. If your website is on an IPv4 connection, it won’t get traffic from IPv6 sites/users, and the reverse is also true.



Google, Facebook, Yahoo!, Akamai and Limelight Networks were among some major organization that offered their content over IPv6 for a 24hour ‘test flight’.
India will start using IPv6 from March 2012, according to a new roadmap released by the Indian Government.

  1. IPv6 will overtake IPv4 surely.

  3. no IPv4 will not vanish. It has no connection with IPv6 both of them will have separate traffic.
