Introductory Remarks from Innovation ‘08

Here's my opening remarks from Media Access Project's Innovation '08 in Santa Clara this morning. A DVD will be available shortly. This was a lively discussion, with Google and Vuze on the case. Good morning and welcome. My name is Richard Bennett and I'm a network engineer. I've built networking products for 30 years and contributed to a dozen networking standards, including Ethernet and Wi-Fi... I'm opposed to net neutrality regulations because they foreclose some engineering options that we're going to need for the Internet to become the one true general-purpose network that links all of us to each other, connects all our devices to all our information, and makes the world a better place. Let me explain. more

Port 25 Blocking, or Fix SMTP and Leave Port 25 Alone for the Sake of Spam?

Larry Seltzer wrote an interesting article for eWeek, on port 25 blocking, the reasons why it was being advocated, and how it would stop spam. This quoted an excellent paper by Joe St.Sauver, that raised several technically valid and true corollaries that have to be kept in mind when blocking port 25 -- "cough syrup for lung cancer" would be a key phrase... Now, George Ou has just posted an article on ZDNET that disagrees with Larry's article, makes several points that are commonly cited when criticizing port 25 blocking, but then puts forward the astonishing, and completely wrong, suggestion, that worldwide SPF records are going to be a cure all for this problem. Here is my reply to him... more

How the Internet Can Be Enormously Accelerated Without Fiber-Optic Cables or LEO Satellites

We got used to it: if we open a website, it's always like stop and go on a high-traffic highway or city traffic jam. At some point, we will reach the destination. The constant stalling is due to a traffic rule for the Internet called TCP (Transmission Control Protocol). The TCP/IP protocol family comes from the American defense industry. It was introduced by DARPA (Defence Advanced Research Projects Agency) in the early 1970s. At that time, no one had the Internet as the need of the masses on the screen. more

IPv6: Extinction, Evolution or Revolution?

For some years now the general uptake of IPv6 has appeared to be "just around the corner". Yet the Internet industry has so far failed to pick up and run with this message, and it continues to be strongly reluctant to make any substantial widespread commitment to deploy IPv6. Some carriers are now making some initial moves in terms of migrating their internet infrastructure over to a dual protocol network, but for many others it's a case of still watching and waiting for what they think is the optimum time to make a move. So when should we be deploying IPv6 services? At what point will the business case for IPv6 have a positive bottom line? It's a tough question to answer, and while advice of "sometime, probably sooner than later" is certainly not wrong, it's also entirely unhelpful as well! more

A Balkanized Internet Future?

Joi Ito has an important post [also featured on CircleID] on how the internet is in danger of becoming balkanized into separate "internets". He's not the only person who's concerned. Greg Walton worries about Regime Change on the Internet. My friend Tim Wu, a law professor specializing in international trade and intellectual property, has written an article for Slate: The Filtered Future: China's bid to divide the Internet... more

AFNIC and DNS Server Redelegation

As an American, I could go for the ignorant stereotyping of the French. But being the good global citizen I try to be, I'll just see if someone can tell me if I'm missing something here, or if indeed AFNIC has lost its mind. I recently requested for one of my .FR domains to be delegated to new DNS servers. I got everything set up at my new DNS provider. But, AFNIC won't perform the transfer because of the following "fatal" reason... more

Removing Need at RIPE

I recently attended RIPE 66 where Tore Anderson presented his suggested policy change 2013-03, "No Need -- Post-Depletion Reality Adjustment and Cleanup." In his presentation, Tore suggested that this policy proposal was primarily aimed at removing the requirement to complete the form(s) used to document need. There was a significant amount of discussion around bureaucracy, convenience, and "liking" (or not) the process of demonstrating need. Laziness has never been a compelling argument for me and this is no exception. more

Dr. Peering Commits Malpractice on Net Neutrality

At Tier1 Research, we hate to call out individuals for wrongdoing, but once in a while, it's absolutely necessary. At the moment, the Federal Communications Commission (FCC) is in the middle of the rulemaking process for network neutrality, a complex endeavor. While Tier1 is against interference from regulators as a concept, the proposed rulemaking document from the FCC, while vague, is not completely unreasonable... more

A Question of DNS Protocols

One of the most prominent denial of service attacks in recent months was one that occurred in March 2013 between Cloudflare and Spamhaus... How did the attackers generate such massive volumes of attack traffic? The answer lies in the Domain Name System (DNS). The attackers asked about domain names, and the DNS system answered. Something we all do all of the time of the Internet. So how can a conventional activity of translating a domain name into an IP address be turned into a massive attack? more

Searching Under Lampposts with DKIM

Email is a complex service and email abuse adds confusing deceptions. Worse, like postal mail and even telephone service, Internet mail is inherently open, flexible and even anonymous, making things much easier for abusers. Bad actors hide their true identity and their true purpose. Most other communication tools for users also are also quite open, and problems with email are being replicated elsewhere, such as instant messaging and social media. more

Challenges in Anti-Spam Efforts

Without commenting on the particulars as they relate to Goodmail -- especially since I am on the advisory board for Habeas, a competitor -- let me note that public discussion is largely missing the nature of the current Internet mail realities and the nature of the ways we can deal with them. There are two articles in the current issue of the Internet Protocol Journal, of which I wrote one, that provide some useful background about this reality. Simply put, Internet mail needs to sustain spontaneous communications... more

Could IP Addressing Benefit from the Introduction of Competitive Suppliers?

An article written by Paul Wilson, Director General of Asia Pacific Network Information Centre (APNIC), and Geoff Huston, Senior Internet Research Scientist at APNIC. "In recent months proposals have been made for the introduction of competition into the system of allocation of IP addresses. In particular, calls have been made for new IP address registries to be established which would compete with the existing Regional Internet address Registries (RIRs). Specific proposals have been made by Houlin Zhao of the ITU-T and by Milton Mueller of the Internet Governance Project, both of which propose that the ITU itself could establish such a registry group, operating as a collection of national registries." ...It would appear that part of the rationale for these proposals lies in the expectation that the introduction of competition would naturally lead to outcomes of "better" or "more efficient" services the address distribution function. This article is a commentary on this expectation, looking at the relationship between a competitive supply framework and the role of address distribution, and offering some perspective on the potential outcomes that may be associated with such a scenario for IP addresses, or indeed for network addresses in general. more

The Invisible Hand vs. the Public Interest in IPv4 Address Distribution

In the efforts to promote the public interest over that of monied interests in Internet Governance few issues are clear cut. One issue that has recently been discussed is that of requiring a "needs assessment" when transferring IP addresss blocks from one organisation to another (in the same or different RIR regions) or indeed when requesting IP resources from your friendly RIR. more

Refutation of the Worst IANA Transition FUD

Of all the patently false and ridiculous articles written this month about the obscure IANA transition which has become an issue of leverage in the partisan debate over funding the USG via a Continuing Resolution, this nonsense by Theresa Payton is the most egregiously false and outlandish. As such, it demands a critical, nearly line by line response. more

At the ARIN Meeting

I have been attending the American Registry for Internet Numbers (ARIN) meeting in Toronto. ARIN is one of the RIRs, i.e., the Internet address registry and policy making authority for North America. Although I have observed and participated on RIR lists for some time and interacted with RIR representatives at ICANN, WSIS and IGF, this is the first time I have been able to attend a meeting. I'm glad I did. more
