  • Whatever happened to the IPv4 address crisis?

    In February 2011, the global Internet Assigned Numbers Authority (IANA) allocated the last blocks of IPv4 address space to the five regional Internet registries. At the time, experts warned that within months all available IPv4 addresses in the world would be distributed to ISPs.

  • Not IPv6-ready? It's time to start planning

    According to the Internet Society, thousands of companies and millions of websites are now permanently deploying IPv6. So it's safe to say the Internet is officially no longer a homogeneous IPv4-only Internet - it is a dual-protocol IPv4-IPv6 Internet. While the proportion of IPv6 Internet traffic is relatively small today, the composition of today's Internet is already shifting.

  • Adopt IPv6 soon or be sorry later, says Internet Society's Leslie Daigle

    A dozen of the world's largest internet companies - including Facebook, Google and Comcast - have committed to June 6, 2012, as the start date for their production deployments of IPv6, an upgrade to the internet's main communications protocol.

  • Wide adoption of IPv6 stalled until 2012, claim analysts

    This was the year that IPv6 garnered major headlines, but 2012 is expected to be the year when the next generation Internet protocol gets widely deployed by US carriers and enterprises.

  • Will the sky fall if you don't deploy IPv6?

    Will the world end if you don't deploy IPv6? Will the internet grind to a screeching halt? Will your computer systems disintegrate into a pile of bits and bytes? In short, no. At least not yet. But you may want to consider a few things.

  • 2012 should be the year of IPv6

    Is 2012 the year to invest in IPv6?

  • What happens if IPv6 fails?

    During the past six months, the Internet engineering community has undertaken an unprecedented effort to promote IPv6 as an urgent and necessary upgrade for network and website operators to allow for the continued, rapid growth of the Internet.

  • Why we shouldn't worry about switching to IPv6 yet

    A lot of coverage of IPv6 over the past few years gives the impression that you need to switch to IPv6 soon. That's not necessarily the case, though, especially for a consumer or a small business.

  • IPv6 has a long way to go

    There's maybe never been a better time to be a network engineer, that is provided you have IPv6 experience.

  • White House to address critical Internet upgrade

    The Obama Administration until now it has ignored one of the biggest issues facing the Internet: the rapid depletion of IPv4 Internet addresses and the imminent need for carriers and content providers to adopt IPv6.

IPv6: A Primer

This paper looks at the evolution of the Internet Protocol1 version 4 (IPv4) into version 6 (IPv6). It includes an introduction to IPv6, an overview of the limitations of IPv4, IPv6 features, key differences between the two protocols and the driving forces behind the need for transition. This is a must read for anyone who wants to understand how IPv6 works and why IPv4 needs to be replaced.

The fundamentals of IPv6

IPv6 is needed to sustain the growth of the internet. IPv4 could in theory be continued to be used and you may be able to work around the address space security limitations of that protocol, but eventually, the cost of staying with IPv4 will outweigh the benefits.

IPv6 ? The Next Generation of Networking

This paper provides an introduction to IPv6 by discussing the potential business benefits resulting from deploying IPv6 technology. To understand how we get these benefits, we look into some of the technical features and advantages of IPv6.

Fw Monitor - A Troubleshooting Tool

Fw monitor is a useful packet capture tool provided by Check Point as a part of VPN-1/FireWall-1. It allows a network troubleshooter to capture packets as they pass through the VPN-1/FireWall-1 Enforcement Module. In order to use the tool, however, the prospective network troubleshooter must first understand the fundamentals of computer networking. We discuss the basics of using the fw monitor utility, including some common optional parameters, which can be very useful. Finally, we end with a series of examples illustrated network troubleshooting.

Transitioning the Public Internet to Internet Protocol Version 6 (IPv6)

IPv6 was developed to improve on its predecessor protocol, addressing many of the limitations that became apparent as the Internet grew. However, to generate improvements, a completely new protocol that was not backwards-compatible with the existing IPv4 specification was required. This created a technological hurdle that few have been willing to clear. Rather, the industry has found ways around the deficiencies of IPv4.
