Slide 2

Is the Internet going to come up short on IP address numbers? Yes and no. For the variant of the Internet Protocol that supports the Internet today (IPv4) there is a constrained measure of unused space remaining. While gauges fluctuate, in view of late patterns it is foreseen that the present pool of unallocated IPv4 locations will be expended at some point around 2010 - 2011. Notwithstanding, a tremendous measure of IP address space exists under IPv6. IPv6, indeed, was particularly intended to settle the address impediments of IPv4. IPv6 addresses have been accessible for portion since 1999 and the RIRs, ICANN , ISOC and others are urging system administrators to apply for IPv6 addresses and execute IPv6 in their systems. Allude to the accompanying declarations from: AfriNIC APNIC ARIN LACNIC

Slide 3

What is IPv6? IPv6 is the new form of the Internet address convention that has been created to supplement ( and in the long run supplant ) IPv4, the variant that supports the Internet today.

Slide 4

What happened to IPv5? Variant 5 of the IP family was a trial convention created in the 1980s. IPv5 (additionally called the Internet Stream Protocol) was never broadly conveyed. Since the number 5 was at that point dispensed, this number was not considered for the successor to IPv4. A few recommendations were proposed as the IPv4 successor, and each was doled out a number. At last, it happened that the one with variant number 6 was chosen.

Slide 5

How does IPv6 tackle the issue of IPv4 address depletion? Essentially by having significantly more deliver space to exceptionally distinguish gadgets that are associated with the Internet. IPv4 has a hypothetical most extreme of around 4 billion locations while IPv6 has an incomprehensible hypothetical greatest: around 340 trillion, trillion, trillion locations . In real utilize, IPv6 locations are organized for steering and different purposes and therefore the quantity of locations accessible is adequately less, yet at the same time to a great degree extensive. For the end client, the huge measure of IPv6 address space implies: Home clients will by and large be given pieces of locations adequate to number different systems and a huge number of gadgets. (Conversely, under IPv4, home clients today regularly get a solitary address.) Enterprises and private ventures will for the most part be offered enough to number a generous number of systems and a huge number of gadgets; while bigger locales will get fundamentally more.

Slide 6

What happens when IPv4 address pool is at last drained? Existing gadgets and systems associated with the Internet through IPv4 locations will keep on working as they do now. Truth be told, IPv4-based systems are relied upon to exist together with IPv6-based systems in the meantime. In any case, for system administrators and different substances that depend on Internet numbering designations, it will turn out to be progressively troublesome and costly (and in the long run restrictively so) to get new IPv4 deliver space to develop their systems. The cost and many-sided quality related with monitoring and overseeing remaining IPv4 address space effectively will likewise increment. Subsequently, organize administrators and ventures should actualize IPv6 keeping in mind the end goal to guarantee long haul arrange development and worldwide network.

Slide 7

Network Address Translation gadgets (NATs) permit numerous PCs to utilize the same IPv4 address. Won't more NATs unravel everything? No . Conveying more NATs is not a sufficient long haul arrangement. NATs can work sensibly well for specific applications, for example, permitting numerous clients in a little office or home system to get to basic Web pages or mail administrations. PCs that sit behind NATs, in any case, don't have genuine end-to-end Internet network. NATs confuse numerous "ongoing" and creative Internet applications, for example, Internet communication and mixed media appropriation. This can be especially risky for substantial corporate systems and clients that need to run complex applications, and furthermore for the individuals who are growing new applications. What's more, diagnosing and settling issues on a system loaded with NATs is for the most part significantly harder than on a system without them. Moreover, as the trouble of getting IPv4 address space builds, it is inescapable that a few locales will just bolster IPv6. IPv6, in this way, will be required to guarantee worldwide network. Beat

Slide 8

But won't regardless we require NATs for security? No. All the security highlights gave in an IPv4 NAT box can be given by an IPv6 switch with firewall capacities, without the need to adjust the address.

Slide 9

Are there different preferences to IPv6 other than expanded address space? The fundamental preferred standpoint of IPv6 is that it gives significantly more address space. Being a later convention, IPv6 has a couple outline enhancements over IPv4, especially in the regions of autoconfiguration, portability, and extensibility. Notwithstanding, expanded address space is the primary advantage of IPv6.

Slide 10

I've heard a few people say IPv6 is more secure than IPv4, while others say it is less secure than IPv4. What is this about? Talks about concerning IPv4 versus IPv6 security regularly concentrate on various parts of system sending. It has been said that IPv6 underpins enhanced security in light of the fact that the determinations command the incorporation of the IP Security (IPsec) suite of conventions in items. In IPv4, including IPsec is discretionary, yet it is ordinarily accessible. Since the IPsec convention suite is intended to be not interested in IP forms, the innovation works by and large a similar route in both IPv4 and IPv6. Thusly, the advantages of utilizing IPsec are comparative in either condition. The expanded address space gave by IPv6 eliminates the need to utilize NAT gadgets , which are inescapable in numerous IPv4 systems. Comprehensively, security is harder to send and investigate when NATs are available in a system as they upset IP layer traceability and consequently security review trails. Moreover, the address reworking that NAT performs is considered by some security conventions to be a security infringement. Therefore, with the expanded address space wiping out the need to utilize NATs, IPv6 possibly encourages sending of end-to-end security. Huge numbers of the IPv6 security issues detailed today need to do with vulnerabilities in individual items, not the IPv6 convention. IPv4 is generally sent and individual IPv4 items have experienced the repeating cycle of finding and settling security vulnerabilities and different bugs. Since IPv6 items are nearly new, they have not profited from comparative experience. Subsequently, security vulnerabilities in IPv6 items should be found and repaired, much the same as for different items. Likewise, the operational practices developed over numerous years for IPv4 systems should be adjusted for IPv6. New practices should be created for the double stack IPv4 and IPv6 condition. This will be quickened as more system administrators send IPv6 and keep on exchanging data about experience and best practices through built up administrators amasses, the IETF Operations region, and different gatherings. Generally, keeping up system security will keep on being a testing undertaking in both IPv4 and IPv6 settings. Neither one of the protocols gives a basic answer for the complexities related with securing systems. Like with IPv4, organize administrators ought to end up distinctly instructed on IPv6 security practices and stay up with the latest with improvements as they plan for and convey IPv6.

Slide 11

Is IPv6 prepared for arrangement now? There are three fundamental viewpoints required in the sending of IPv6: the convention, the items, and the operational practices. The IPv6 Protocol IPv6 has profited from more than 10 years of advancement inside the Internet Engineering Task Force (IETF). The center measures have been steady for a long time and conveyed in both research and operational settings. Notwithstanding the center determinations, IPv6 incorporates countless models that have a more constrained materialness and are just required in particular conditions. Extra improvement work will proceed in these ranges as new issues are found in light of arrangement particular situations. Like the proceeding with development of IPv4, there will dependably be updates and augmentations to IPv6 in light of arrangement experience. Along these lines, despite the fact that the center IPv6 determinations are steady, there will keep on being continuous work on IPv6-related particulars. IPv6 Products The center IPv6 details are turning out to be progressively accessible as a standard piece of items and administration offerings. Notwithstanding, not all items are completely IPv6 able right now and some huge redesign crevices remain, particularly in low-end buyer hardware. Likewise, while numerous product applications and working frameworks (particularly in open source code) have as of now been refreshed for IPv6, not all items (counting some from significant merchants) are completely IPv6 prepared. It is best to check with particular sellers on the IPv6 preparation of their individual items and administrations. What's more, in-house application programming or custom code that interfaces with the system will probably require refreshing for IPv6. IPv6 Operational Practices Operational practices developed over numerous years for IPv4 systems should be adjusted for IPv6. There is developing background in the sending of IPv6 in research systems and R&D ventures, while some generation systems (basically in Japan and Korea) have been running IPv6 for various years. IPv6 activity today, notwithstanding, stays little in contrast with IPv4. As more system administrators send IPv6 and keep on exchanging data about experience and best practices through set up administrators aggregates, the IETF, and different gatherings, the group information level will develop. In rundown, IPv6 is prepared for arrangement, however extra exertion is expected to make its utilization pervasiv
