: While we may take the long distance dialing codes for granted, its idea emanated from an AT&T staff who observed a sharp increase in the number of trunk call requests and reckoned that if the same pace continued, it would require AT&T to employ thousands of additional people just to handle this load. The choice was between increasing the number of people and innovating a system for subscribers to dial long distance on their own. Bell Labs chose the latter and the option of prefixing long distance code was innovated.
The long distance code used STD code. Often it is presumed that regulators are only to simulate the market but the fact is that the regulators also need to stimulate the market and Trai has done well in enhancing the awareness about opportunities, challenges and implementation issues related to migration towards Internet Protocol Version 6 (IPv6) from the prevailing IPv4.
When Vint Cerf (one of the pioneers of Internet) visited India a few years back and was asked to describe how the Internet works. He said, it is like sending a paragraph of a novel through separate post cards in a cost-effective manner such that at the destination, these paragraphs re-align in the correct sequence and the recipient receives the novel in a single piece. In technical jargon, this breaking of information into pieces is called packetisation.
It is often presumed and even stated that the Internet is an unmanaged network but the fact is that it is a managed one, albeit the seemingly random transmission of packets may look very chaotic to anyone looking at it from outside. A bunch of agencies work, manage and maintain the hierarchical addressing system that decides where a particular packet is destined.
Trai has rightly recommended using e-governance as the positive incentive for accelerating use of IPv6 in India and setting up of National Internet Registry (NIR) within the country. Now that we already have IXP (Internet Exchange Point), Root Servers and a market-driven online country top-level domain name (ccTLD) system under the aegis of NIXI (National Internet Exchange of India), it is but natural to host the proposed NIR too within NIXI.
When the Internet was still a reserve of the academicians, researchers and the scientists, IP addresses (there are about 4 billion unique ones possible in the IPv4 system) used to be assigned in thousands and lakhs at a go and were available just for the...
