Internet Protocol version 6 (IPv6) Addressing Overview

Indian Registry for Internet Names and Numbers (IRINN) has started issuing next version of Internet addresses ‘IPv6’, which would make it easy for security agencies to identify each Internet user.

The Internet addresses under the present version IPv4 (Internet Protocol version 4), are limited and service providers often assign single IP address to many users, making it difficult to identify the end user.

APNIC, which is one of the five authorised bodies for issuing Internet addresses, has recognised Indian Registry for Internet Names and Numbers (IRINN) for issuing IP addresses in India.

The new addresses will be multiple times cheaper for companies than IPv4 addresses.

Advantages of IPv6 over IPv4

IPv6 solves the IPv4 public address depletion problem by providing an address space to last well. The business benefit of moving to IPv6 is that mobile cell phones, personal data assistants (PDAs), automobiles, appliances, and even people can be assigned multiple globally reachable addresses.

Connectivity between disjoint networks requires intermediate devices such as NATs or proxy servers. With IPv6, both homes and enterprises will be assigned global address prefixes and can seamlessly connect, subject to security restrictions such as firewall filtering and authenticated communication.

With IPv6, public address prefixes are assigned to regional Internet registries, which, in turn, assign address prefixes to other ISPs and organizations based on justified need. This new address allocation practice ensures that address prefixes will be distributed globally based on regional connectivity needs, rather than by historical origin.

With IPv6, NATs are no longer necessary to conserve public address space, and the problems associated with mapping addresses and ports disappear for developers of applications and gateways.

Unlike IPv4 addresses, IPv6 addresses have a scope, or a defined area of the network over which they are unique and relevant.

IPv6 is a streamlined version of IPv4. Excluding prioritized delivery traffic, IPv6 has fewer fields to process and fewer decisions to make in forwarding an IPv6 packet.

The result of designing IPv6 with security and mobility in mind is an implementation that is a defined standard, has fewer limitations, and is more robust and scalable to handle the current and future communication needs of the users of the Internet.

Background

Internet Service Provider(ISP)

An Internet service provider (ISP) is a business or organization that offers users access to the Internet and related services.

Many but not all ISPs are telephone companies or other telecommunication providers.

They provide services such as Internet access, Internet transit, domain name registration and hosting, dial-up access, leased line access and colocation.

Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.

National Internet Exchange of India (NIXI)(IT)

The National Internet Exchange of India is the neutral meeting point of the ISPs in India.

Its main purpose is to facilitate exchange of domestic Internet traffic between the peering ISP members.

This enables more efficient use of international bandwidth, saving foreign exchange.

It also improves the Quality of Services for the customers of member ISPs, by avoiding multiple international hops and thus reducing latency.

Indian Registry for Internet Names and Numbers (IRINN)(IT)

Indian Government has launched the National Internet Registry which will manage IP address allocations and other internet resources.

NIR has been named Indian Registry for Internet Names and Numbers (IRINN) which is a division in National Internet Exchange of India (NIXI).

NIR functions under Regional Internet Registry (RIR) which is Asia Pacific Network Information Centre in Brisbane, Australia. APNIC manages IP address allocation and other internet resources for the Asia Pacific region.

Earlier IP addresses had to be bought directly from APNIC which proved out to be time consuming and quite expensive. With NIR, buying IP addresses will become up to 70% cheap and will also help the country in cyber crime investigations
