IP VERSION 6 (IPV6)
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP),
the communications protocol that provides an identification and location system for computers on
networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task
Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended
to replace IPv4.
Commonly asked interview questions on Constructors
1.What is IPv6??
Answer :Internet Protocol Version 6 (IPv6) is a network layer protocol that enables data communications over a packet switched network. Packet switching involves the sending and receiving of data in packets between two nodes in a network.
2.Who created IPv6 and how long has IPv6 been available? Is it new?
Answer :The Internet Engineering Task Force (IETF), an international group concerned with developing technical standards that make the Internet work better first published the basic IPv6 protocol in 1998. It has since seen a number of enhancements, such as the addition of mobile IPv6 specifications (in 2004).
3.What is the Internet about to run out of IP address numbers ?
Answer : the version of the Internet Protocol that underpins the Internet today (IPv4) there is a limited amount of unused space remaining. While estimates vary, based on recent trends it is anticipated that the current pool of unallocated IPv4 addresses will be consumed sometime around 2010 – 2011.
4.How much will the transition to IPv6 cost??
Answer :Since network needs and businesses differ, IPv6 transition strategies and related costs will also vary between organisations. Hardware and software vendors are increasingly integrating IPv6 as a standard feature in products, allowing organisations to deploy IPv6 as part of routine upgrade cycles. For many organisations, operational costs, including staff training, and one-time administrative costs to add IPv6 to management databases and documentation, are likely to constitute the majority of the cost of upgrading to IPv6
5.What, specifically, still needs to happen for the industry to effectively transition to IPv6 ?
Answer :The transition to IPv6 will require collaboration across the Internet industry:
Internet service providers, Web companies, hardware vendors and operating system vendors.All major industry players need to take action to ensure products and services are ready for the transition. For example, Internet service providers need to make IPv6 connectivity available to their users, Web companies need to offer their sites and applications over IPv6, operating system vendors may need to implement specific software updates, backbone providers may need to establish IPv6 peering with each other, and hardware and home gateway gateway manufacturers may need to update firmware.
