L-Root instance Kolkata

It has been long we were trying to bring L-root instance in eastern part of India, and I am extremely proud being associated in this initiative with ISOC Kolkata Chapter in bringing the first L-Root node in India and to start contributing to the stability and resiliency of the core Internet infrastructure. As India’s internet penetration expands, it will be important for other root server instances to be established across the country.

About Root Servers

Root servers are part of the Domain Name System (DNS), a worldwide distributed database that is used to translate worldwide unique domain names such as www.icann.org to other identifiers. The DNS is an important part of the Internet because it is used by almost all Internet applications.

The root name servers publish the root zone file to other DNS servers and clients on the Internet. The root zone file describes where the authoritative servers for the DNS top-level domains (TLD) are located; Root servers are operated by twelve organisations often referred to as the “root server operators”. They are

A – VeriSign Global Registry Services
B – Information Sciences Institute
C – Cogent Communications
D – University of Maryland
E – NASA Ames Research Center
F – Internet Systems Consortium, Inc.
G – U.S. DOD Network Information Center
H – U.S. Army Research Lab
I – Autonomica/NORDUnet
J – VeriSign Global Registry Services
M – WIDE Project

The letters A-M represent the 13 numeric IPv4 addresses at which the service is provided. Each operator is repsonsible for providing reliable DNS service to the Internet at large from their address. Some operators still provide the service from one location with one or more physical machines. Other operators provide the service from multiple locations using a method called “anycast”. The actual root name servers machines are located at more than 500 locations across the world.

More information about most operators can be found via www.root-servers.org/

Hosting more root instance in India, essentially bring security, resiliency in core Internet infrastructure for the country as more and more DNS root queries are getting resolved locally.
