When
operational Internet was launched in 1983, the author never imagined if there
will be billions of devices and users to be connected. But now, almost three
decades later, the Internet now serves nearly 2.5 billion people and 11 billion
devices worldwide.
To
connect to the Internet, each device must have an IP address that identifies
each computer, mobile phone, tablet, and other devices. IP addresses allow
devices to locate and communicate with each other online. Without the IP
address, we will not be able to connect to the Internet, visiting websites,
checking email or streaming video. Now, the Internet began to run out of IP
addresses. Internet that we use so far has room for 2 to the power 32
addresses, or about 4.3 billion IP addresses. But a new IP, IPv6, has a wider
space with 2 power of 128 addresses, or about 340 trillion, trillion, trillion
(340 followed by 36 digits 0 behind it). This amount is enough for future
growth.
In February 2011, the Internet Assigned
Numbers Authority (IANA) run out of addresses to allocate addresses to Regional
Internet Registries. If IPv6 is not implemented, you will be sharing an address
with some more. Today (06.06.2012) is today the official launch of IPv6
.Coordinated by the Internet Society , Internet Service Provider (ISP) and the
hardware manufacturers will enable IPv6 permanently, parallel to IPv4.
