Questioning "Net Neutrality"

I'm kinda foxed by the some of the discussion going on about "Net Neutrality". The internet was designed from the outset not to be content neutral. Even before there was an IP protocol there were precedence flags in the NCP packet headers. And the IP (the Internet Protocol) has always had 8 bits that are there for the sole purpose of marking the precedence and type-of-service of each packet. It has been well known since the 1970's that certain classes of traffic -- particularly voice (and yes, there was voice on the internet even during the 1970's) -- need special handling... more»

How a Security Specialist Fell Victim to Attack

Our systems are protected by state of the art security systems. Our SPAM filter is a hardware device that is nearly 100% effective. It also helps in protecting against Spyware and other malicious code. Our Firewall is similar to those you would find in large corporations. Our Anti-Virus system has served us well and we've not had problems with virus for years. ...Two weeks ago, I received approximately twenty e-mails requesting the review and approval of Defending The Net articles published on other sites. I thoroughly review the e-mails to make sure they seem legitimate... more»

The Ultimate Solution to Internet Governance: Let ITU and ICANN compete

Controversies over ICANN led to the creation of the Working Group on Internet Governance, but so far there have been few specific proposals for change. The Internet Governance Project has entered that breach with a new policy paper: "What to Do About ICANN: A Proposal for Structural Reform." The proposal, by Hans Klein and myself, proposes three clean, clear but probably controversial solutions to the criticisms that have been made of ICANN. more»

AOL Fires Across the Bow of Spam-Friendly ISPs

The North American Network Operators Group (NANOG) conference, a gathering of Internet Service Provider (ISP) engineers and vendors convenes three times a year for mostly technical conversation along with social networking. The recent NANOG conference in Reston Virginia saw some unusually direct talk about Spam and the ISPs that tolerate it from America Online's Postmaster, Charles Stiles. more»

Blissful Ignorance: Placement Prostituting the Press

Andrew McLaughlin, in his excellent dismemberment of the BBC's report on the "IPv4 address crisis", is observing not a random piece of sloppy research, but the success of settled policy. That policy, pursued by public relations companies serving information technology and telecommunications (IT&T) companies, is simple to sum up: "identify, support and encourage technically ignorant journalism". It centres around the most valuable word in the lexicon of the public relations firm: "placement"...A key characteristic of the "placement" story is its conformance to a template...With one search, I found a CNET story published in July with quite startling parallels to the BBC story... more»

FCC to Hold Two December Workshops on PSTN Transition to New Technologies

The US Federal Communications Commission (FCC) recently issued a public notice that it will be holding two workshops on the transition of the public switched telephone network (PSTN) to "new technologies" such as voice-over-IP (VoIP). The workshops will be held on December 6 and 14, 2011, at the FCC's office in Washington, DC. The public notice states the goal as... more»

IPv4 Historical Imbalances and the Threat to IPv6

It is an open secret that the current state of IPv4 allocation contains many accidental historical imbalances and in particular developing countries who wish to use IPv4 are disadvantaged by the lack of addresses available through ordinary allocation and are forced into purchasing addresses on the open market. As most of the addresses for sale are held by organisations based in the developed world, this amounts to a transfer of wealth from the developing world to the developed world, on terms set by the developed world. more»

IPv6 in Slovak Academic Network

The main reason for developing a new internet protocol was based on lack of address; however this was not the only reason. Unfortunately, many people think of IPv6 only as enormous address space, but there are a lot of other advantages, for example... authorizations and authentication function are implemented directly in the protocol and are mandatory... automatic configuration of network interfaces based on their physical address... protocol itself recognizes data streams which must be transmitted in real time, and the data must be processed with highest priority... more»

Mexico to Stop IPv4 Address Assignments Starting 2011

NIC Mexico, manager of the country code top-level domain .MX and registrar of IP addressees to Internet users in Mexico, says in a report today that lifetime for IPv4 addresses is projected to finish on 1/1/11 after which all the new IP addresses will be allocated on IPv6. more»

Discussion at the Internet Governance Forum in Geneva

While travelling home from Geneva, I was thinking quite a lot on the relationship between a ccTLD (registry) and a Country. This is because many countries are starting to talk louder and louder about the responsibilities Countries have on critical infrastructure, or (possibly more important) the management of the critical infrastructure. Will for example any (none?) of ccTLD operators (servers) sustain a denial of service attack of a scale similar to the attack on the root servers? What can ccTLD operators do to resist the malicious attacks? Should this be discussed? more»

Geographic Implications of DNS Infrastructure Distribution

The past several years have seen significant efforts to keep local Internet communications local in places far from the well-connected core of the Internet. Although considerable work remains to be done, Internet traffic now stays local in many places where it once would have traveled to other continents, lowering costs while improving performance and reliability. Data sent directly between users in those areas no longer leaves the region. Applications and services have become more localized as well, not only lowering costs but keeping those services available at times when the region's connectivity to the outside world has been disrupted... The recently published paper, "Geographic Implications of DNS Infrastructure Distribution" focuses on the distribution of DNS infrastructure. more»

Are We Slowly Losing Control of the Internet?

I have long been intrigued by the question of how do we turn the internet into a lifeline grade infrastructure... My hope that this will occur soon or even within decades is diminishing. Most of us observe, almost daily, how even well established infrastructures tend to crumble when stressed, even slightly... I was at the O'Reilly Etel conference last week. The content was impressive and the people there were frequently the primary actors in the creation and deployment of VOIP. However, not once during the three days did I hear a serious discussion by a speaker or in the hallways about how this evolving system would be managed, monitored, diagnosed, or repaired. more»

Addressing the Future Internet

What economic and social factors are shaping our future needs and expectations for communications systems? This question was the theme of a joint National Science Foundation (NSF) and Organisation for Economic Co Operation and Development (OECD) workshop, held on the 31st January of this year. The approach taken for this workshop was to assemble a group of technologists, economists, industry, regulatory and political actors and ask each of them to consider a small set of specific questions related to a future Internet. Thankfully, this exercise was not just another search for the next "Killer App", nor a design exercise for IP version 7. It was a valuable opportunity to pause and reflect on some of the sins of omission in today's Internet and ask why, and reflect on some of the unintended consequences of the Internet and ask if they were truly unavoidable consequences... more»

A Fundamental Look at DNSSEC, Deployment, and DNS Security Extensions

In looking at the general topic of trust and the Internet, one of the more critical parts of the Internet's infrastructure that appears to be a central anchor point of trust is that of the Domain Name Service, or DNS. The mapping of "named" service points to the protocol-level address is a function that every Internet user relies upon, one way or another. The ability to corrupt the operation of the DNS is one of the more effective ways of corrupting the integrity of Internet-based applications and services. If an attacker can in some fashion alter the DNS response then a large set of attack vectors are exposed. ...The more useful question is whether it is possible to strengthen the DNS. The DNS is a query -- response application, and the critical question in terms of strengthening its function is whether it is possible to authenticate the answers provided by the DNS. DNSSEC provides an answer to this question. more»

Would the Real Network Neutrality Please Stand Up?

I'm sure this is something that's been raked over before, but I don't see a common understanding of what 'Net Neutrality' actually is. Despite many of the Internetorati demanding it by law. There appear to be several different camps, which you could paint as "bottom of IP", "middle" and "top". The bottomistas would see enforced Internet Protocol itself as a premature optimisation and violation of the end-to-end principle. Unhappy that you only get IPv4 or IPv6? Still grumpy that you only have IPv4 and not even IPv6? Really miserable that your VoIP packets are staggering under the poisonous load of IPv6 headers? You're a bottomista. more»
