Google Officially Announces Introduction of IPv6

Google search is available over IPv6 at ipv6.google.com (you'll need an IPv6 connection to view it)... From the official blog: "We hope that by allowing every computer and mobile device on the network to talk to each other directly -- an idea known as the "end-to-end principle" that was crucial to the original design of the Internet -- IPv6 will allow the continued growth of the Internet and enable new applications yet to be invented." more

IPv4 Shortage and Trading Concerns as Hot Marketable Goods

With IPv4 addresses in short supply, they could become increasingly interesting and marketable goods. This is a concern for Regional Internet Registries (RIR) that are in charge of managing IP address allocations. Heise Online reports: "If they officially permit transfers or sales in the future, they will be implicitly accepting commercialization and privatization. Any attempt to insist on the return of addresses to the RIRs could drive trading, which is probably inevitable, underground..." more

Significant Chunk of IP Address Space Hijacked by Notorious Mass Emailing Company

Internet address space long ago issued to San Francisco Bay Packet Radio, an organization that was involved way back in the 1970s in testing ARPANET, a predecessor to the global commercial Internet that we all use today. That organization was given the rights to do whatever it wanted with 134.17.0.0/16 address block. That entire swath of Internet space is now registered to an entity in Westminster, Colo., called SF Bay Packet Radio LLC, but except for a similar name, this company has no relation to San Francisco Bay Packet Radio... ? more

The End of End-to-End?

One of the major principles of the architecture of the Internet was encapsulated in a paper by Saltzer, Reed and Clark, "End-to-End Arguments in System Design". This paper, originally published in 1981, encapsulated very clearly the looming tension between the network and the application: "The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible." At the time this end-to-end argument was akin to networking heresy! more

CAIDA and ARIN Release IPv6 Survey

The Cooperative Association for Internet Data Analysis (CAIDA) and the American Registry for Internet Numbers (ARIN) presented the results [PDF] of a recent IPv6 survey at the ARIN XXI Public Policy Meeting in Denver on April 7th. The survey involved over 200 respondents from a blend of Government, commercial organizations (including ISPs and end users), educational institutions, associations, and other profit and non-profit entities. The purpose of the survey, conducted between March 10th and 24th, was to capture IPv6 penetration data in the ARIN region... more

Proposal to Allow IPv4 Address Trading Could Prolong IPv6

The American Registry for Internet Numbers (ARIN) is considering sweeping changes to the way they distribute IP addresses that could allow network operators to make money by transferring unused blocks of IPv4 address space to others in need. One result could be lessened incentive to move to IPv6 any time soon. more

16 Million Unused IPv4 Address Just Made Available for Use on the Internet

ICANN is reported to have found a little breathing room in the IPv4 address space with its recovery of a block of 16 million IPv4 addresses. The IP addresses recovered were once used to connect older protocol packet-data networks with the fledgling Internet. The block of addresses, technically referred to as 14.0.0.0/8, is also known as Net-14. more

NIST Releases a Profile for IPv6 in the U.S. Government for Comment - Comments Due Feb. 29

The National Institute for Standards and Technology (NIST) has released a second draft of a proposed standards profile to support the implementation of IPv6 by government agencies. "NIST developed the 'profile' to help ensure that IPv6-enabled federal information systems are interoperable, secure and able to co-exist with the current IPv4 systems." ...The White House's Office of Management and Budget declared in 2005 that all federal agencies shall migrated to IPv6 by June 30, 2008... more

Most IT Professionals See No Compelling Benefits to IPv6, Says New Survey

Only 16% of IT professionals consider IPv4 address depletion "a huge concern that has or will soon force us to migrate to IPv6," according to a BT INS survey of 310 IT professionals that was conducted in December 2007. A whopping 26% of IT professionals felt IPv4 address depletion was "no concern.'' more

Fast Flux Hosting a Mounting and Serious Threat to Online Activities

ICANN Security and Stability Advisory Committee (SSAC) has released a report [PDF] describing the technical aspects of fast flux hosting and fast flux service networks. From the report: "Fast flux" is an evasion technique that cyber-criminals and Internet miscreants use to evade identification and to frustrate law enforcement and anticrime efforts aimed at locating and shutting down web sites used for illegal purposes. more

Internet Governance: The Issue, The Myths, The Problems, The Solutions

I have written a short paper on the topic of Internet Governance. Since it includes a number of resources, it would be easier for me to just point to a link with the document itself. Below are some selected excerpts from the document. "Several myths have been spreading around the World Summit on the Information Society (WSIS), but especially after the first Internet Governance Forum (IGF): The critical Internet resources (CIR) consist only of the IP addresses and the domain name system... There are only 13 root servers..." more

IPv4 Address Exhaustion and a Trading Market

There are discussions starting within the Regional Internet Registries (RIRs) about the creation of trading market in IPv4 addresses as we approach the inevitable exhaustion of unallocated addresses. The view being put forward is basically "this is likely to happen anyway and by discussing it now, we can ensure it happens in an orderly way". When I first heard this idea I was a bit surprised. The RIRs are policy based bodies and so a shift to a trading market appears to be an abandonment of that policy base. However I have been partly corrected on that. more

ARIN Statement on the Future of Addressing Policy

ARIN has just released a statement on the future of addressing policy. Specifically addressing the future of IPv4 addressing. What ARIN does is to emphasize the current policies and say they will be enforced even stronger than today if needed. I.e. there is no announcement of a change in policy. more

ARIN Calls for Faster Migration to IPv6

InformationWeek reports that the American Registry for Internet Numbers (ARIN) has called for a faster migration to the new Internet Protocol, IPv6. "We must prepare for IPv4's depletion, and ARIN's resolution to encourage that migration to IPv6 may be the impetus for more organizations to start the planning process," said John Curran, chairman of ARIN's Board of Trustees, in a statement. more

Ready or Not… Here Come the IRC-Controlled SIP/VoIP Attack Bots and Botnets!

A story... ZZZ Telemarketing (not a real name) is locked in a heated fight with their bitter rival, YYY Telemarketing (also not a real name), to win a very large lead generation contract with Customer X. Customer X has decided to run a test pitting the two companies against each other for a week to see who can generate the most leads. The ZZZ CEO has said to his staff that it is "do or die" for the company. If they fail to win the contract, they will have to shut down -- they need to do "whatever it takes" to win over YYY. A ZZZ staffer discovers that part of why YYY has consistently underbid them is because they are using SIP trunks to reduce their PSTN connection costs. But the staffer also discovers that YYY is using very cheap voice service providers who run over the public Internet with no security... more
