IPv6: A 2012 Report Card

The Gogonet Live conference in San Jose witnessed outstanding presentations by several federal administrations including Veteran Affairs, NASA and SPAWAR, sharing their experience and progress towards IPv6 adoption. Furthermore, the NIST compliance report leaves no agency any place to hide. The report card is there for everybody to see. In spite of regular jabs and criticisms, the US Federal Government has done a remarkable job. more

An Update on IPv6

In the coming weeks another Regional Internet Registry will reach into its inventory of available IPv4 addresses to hand out and it will find that there is nothing left. This is by no means a surprise, and the depletion of IPv4 addresses in the Internet could be seen as one of the longest slow motion train wrecks in history. The IANA exhausted its remaining pool of unallocated IPv4 addresses over four years ago in early 2011, and since then we've seen the exhaustion of the address pools in the Asia Pacific region in April 2011, in the European and the Middle Eastern region in September 2012, in Latin America and the Caribbean in May 2014 and now it's ARIN's turn... more

10 Reasons Why Involving Government in Spam Control is a Bad Idea

1. Many jurisdictions already have laws which cover abuse of computer systems and networks -- and spam is of course abuse. These laws are only sporadically enforced, however, usually when a sufficiently visible/powerful entity is the aggrieved party. Adding more laws (a) is redundant and (b) does not increase enforcement. 2. Laws are only enforced as law enforcement has resources available. Spam/abuse is not a high priority unless a sufficiently visible/powerful entity makes it so, and those cases are rare. more

Using Domain Filtering To Effect IP Address Filtering

In Taking Back The DNS I described new technology in ISC BIND as of Version 9.8.0 that allows a recursive server operator to import DNS filtering rules in what ISC hopes will become the standard interchange format for DNS policy information. Later I had to decry the possible use of this technology for mandated content blocking such as might soon be the law of the land in my country. I'm a guest at MAAWG this week in San Francisco and one of the most useful hallway discussions I've been in so far was about the Spamhaus DROP list. more

Can We Stop IP Spoofing? A New Whitepaper Explores the Issues

In March 2013, Spamhaus was hit by a significant DDoS attack that made its services unavailable. The attack traffic reportedly peaked at 300Gbps with hundreds of millions of packets hitting network equipment on their way. In Q1 2015, Arbor Networks reported a 334Gbps attack targeting a network operator Asia. In the same quarter they also saw 25 attacks larger than 100Gbps globally. What is really frightening about this is that such attacks were relatively easy to mount. more

Annual Global IP Traffic Will Exceed Two-Third of a Zettabyte in 4 Years

Annual global IP traffic will pass two-thirds of a zettabyte in four years according the Cisco's Visual Networking Index report. The economic downturn has only slightly tempered traffic growth and the global IP traffic is expected to quintuple from 2008 to 2013. Cisco predicts IP traffic to grow at a compound annual growth rate (CAGR) of 40%. more

Technology Adoption in the Internet

How are new technologies adopted in the Internet? What drives adoption? What impedes adoption? These were the questions posed at a panel session at the recent EuroDiG workshop in June. In many ways, this is an uncomfortable question for the Internet, given the Internet's uncontrolled runaway success in its first two decades. The IPv4 Internet was deployed about as quickly as capital, expertise, and resources could be bought to bear on the problem... more

IPv6: How Do the Top Ranked Tier-One ISP’s Perform?

A look at the world's dozen or so Tier one ISP's who run global networks and sell wholesale IP transit to national and regional 'tier two ISP's' is quite revealing when taking into account how their ranking evolved over the last five years. They peer with each other at selected locations while competing ferociously in an increasingly commoditized market. more

U.S. Moving Forward with ENUM

One of the pieces of infrastructure that makes all kinds of networks work and yet gets very little attention is the directory. Directories are big business. For example, there's directory of telephone numbers run by NeuStar, Inc. NeuStar has annual revenues of $92 million. Now, according to Light Reading, AT&T Corp. and MCI Inc., together with unidentified cable companies, telephone companies, and ISPs are preparing to form a Limited Liability Corporation (LLC) that will run a process to define a new company that will run ENUM. more

OECD Reports on State of IPv6 Deployment for Policy Makers

OECD, Organization for Economic Co-Operation and Development, has released a report for policy makers assessing the level of IPv6 deployment around the world. "[T]he timely deployment of IPv6 by network operators and content/application providers is an increasing priority for all Internet stakeholders. In terms of public policy, IPv6 plays an important role in enabling growth of the Internet to support further innovation. In addition, security, interoperability and competition issues are involved with the depletion of IPv4." more

80% of Spam Originating from Home PCs

The majority of spam -- as much as 80 per cent of all unsolicited marketing messages sent -- now emanates from residential ISP networks and home user PCs. This is due to the proliferation of spam trojans, bits of surreptitious malware code embedded in residential subscriber PCs by worms and spyware programs. Worm attacks are growing in frequency because they provide a fast means of infecting a vast number of computers with spam trojans in a very short period of time. It's no surprise that many service providers report an upsurge in spam traffic immediately following a worm attack. more

Myanmar Internet Shutdown

There have been lots of press stories in the last day reporting on what the Internet shutdown in Myanmar looked like for people there, and that's the important story. This is what it looked like to the rest of the world, from an Internet infrastructure standpoint. The connection between Myanmar and the rest of the world appears to be turned back on, at least temporarily. The 45 megabit per second circuit connecting Myanmar to Kuala Lumpur that is Myanmar's primary connection to the Internet came back up at 14:27 UTC today. It had mostly been "hard down," indicating either that it had been unplugged or that the router it was connected to was turned off, with the exception of a few brief periods since September 28. Myanmar's country code top level domain, .MM, disappeared... more

Why 2008 Was a Milestone Year for IPv6

The beginning of the year saw IPv6 added to the DNS root, closing a major hole for IPv6-only communication. In mid-year, the US federal government's IPv6 mandate came into effect, requiring all federal IP backbones to support IPv6. While the mandate didn't have anywhere near the effect that many had hoped for, it did spur many vendors to add IPv6 support to their products. The amount of observed IPv6 traffic increased considerably, but we still lack good data for how much IPv6 is being used. So, where were we at the end of 2008? more

A Primer on IPv4, IPv6 and Transition

There is something badly broken in today's Internet. At first blush that may sound like a contradiction in terms. After all, the Internet is a modern day technical marvel. In just a couple of decades the Internet has not only transformed the global communications sector, but its reach has extended far further into our society, and it has fundamentally changed the way we do business, the nature of entertainment, the way we buy and sell, and even the structures of government and their engagement with citizens. In many ways the Internet has had a transformative effect on our society that is similar in scale and scope to that of the industrial revolution in the 19th century. How could it possibly be that this prodigious technology of the Internet is "badly broken?" more

Is There a Positive Business Case for IPv6? We Are About to Find Out, If You Help Us…

Large-scale IPv6 deployments suggest that IPv6 is at least a technical success, the technology works. Time to visit the other important question: does it work commercially. Does IPv6 really come with a positive business case? We are about to find out, if you help us... The Internet technical community has spent about two decades making IPv6 work on a technical level. We have developed the protocol, modified and expanded a few others; we set up the registry system and distributed the addresses. more
