Nepal Telecommunications Authority (NTA) is going to study Internet
Protocol version 6, a new addressing system that will allow more
internet addresses to be assigned than the current version 4, which is
the dominant communications protocol for most Internet traffic as of
2012.
“The new web addressing system — Internet Protocol version 6 — will
succeed the present addressing system — Internet Protocol version 4 —
that will run out of internet addresses in some years,” according to the
regulator.
Each device on the Internet like a computer or mobile telephone,
must be assigned an Internet Protocol — the primary protocol that
establishes the Internet — address in order to communicate with other
devices. With the ever-increasing number of new devices being connected
to the Internet, there is a need for more addresses than the current
version 4 can accommodate.
More than 100 countries throughout the world have already started
the process of being migrated to the Internet Protocol version 6,
assistant director at the authority Baburam Dawadi said, adding that the
regulator has just started the process.
Internet Protocol version 4, which the country is using at present,
will be exhausted due to excessive Internet users, he said. “All the
countries should move to Internet Protocol version 6 before the current
system will run out of addresses.”
‘Internet Protocol version 4 exhaustion’ doesn’t mean that the
internet will stop working, instead, it describes when there will be no
more unallocated addresses available.
According to Asia-Pacific Network Information Centre – which is the
regional internet registry for the Asia-pacific region — Internet
Protocol version 6 will replace the current version.
Asia Pacific Network Information Centre — the internet registry for
India — has run out of Internet Protocol version 4 addresses with barely
a few left for transition to Internet Protocol version 6. “The
department of information and technology had directed all states and the
central government to switch to Internet Protocol version 6 by March
2012 but the plan is still running behind schedule.”
The Authority will appoint expert to evaluate current situation and
process of migration within a month. It has incorporated the plan of
completing study in its yearly plan too, Dawadi said, adding that the
authority will take concrete decision regarding migration by the end of
current fiscal year.
Internet Protocol version 4 can support only about 4.29 billion IP
addresses and newer devices may not be able to access the internet as
the unique numbers run out. The IP address space is managed by the
Internet Assigned Numbers Authority globally, and by five regional
Internet registries responsible in their designated territories for
assignment to end users and local Internet registries, such as Internet
service providers.
