Huge Increase in Spam in October Email

You may have read reports that the total amount of spam is on the decline. Don't believe them. In the month of October, I saw the amount of spam in my traps here roughly double, from about 50,000 per day to 100,000/day now. In conversations with managers at both ISPs and corporate networks, I'm hearing the same thing. more

Problems With Defining Jurisdiction on the Internet

The term "jurisdiction" has various definitions in law, but for our purposes here we can say it is the power of some legal body to exercise its authority over a person or subject matter or territory. In the Internet today, it is territory that gives rise to many major issues. As in real estate, what matters in jurisdiction is "location, location, location". When the Internet and trademark rights began to intersect, it quickly became apparent that traditional concepts of the jurisdiction of courts and legislatures would be seriously strained by situations where a registrant in one country could use a registrar in a second country to register a domain name in yet a third country. more

The End of the “Skype as Bandit” Era

And so it ends... Skype was always always a fun company to write about because they were always a bit of a rogue. The scrappy little startup that took on the megacorps of the telecom industry... and won in so many ways... look at their leading % of international calls... or the fact that per-minute call costs are now very clearly being commoditized down to zero... more

Registrar Market Share: An Alternative Perspective

In the past, most measurements of registrar market share have tracked overall registrar shares -- number of domains registered by a registrar divided by number of domains registered by all registrars. In this article, I propose some alternatives -- particular subsets of domains in which to measure registrar market shares, providing a basis for comparison with overall market shares. Results vary dramatically across these subsets, with implications on the future customer retention rates of the corresponding registrars.  more

Why Is It So Hard to Run a Bitcoin Exchange?

One of the chronic features of the Bitcoin landscape is that Bitcoin exchanges screw up and fail, starting with Mt. Gox. There's nothing conceptually very hard about running an exchange, so what's the problem? The first problem is that Bitcoin and other blockchains are by design completely unforgiving. If there is a bug in your software which lets people steal coins, too bad, nothing to be done. more

ICANN and Your Internet Abuse

In spite of the material we were presented with in Durban something has gone very wrong inside of ICANN Compliance. KnujOn has published a report which demonstrates that ICANN Compliance appears to completely collapse between September 2012 and December 2012. Following December 2012, ICANN seems to stop responding to or processing any complaints. It is around this time certain compliance employees start disappearing. This was not limited to the Sydney office as some would have us believe... more

Internet Governance Outlook 2021: Digital Cacaphony in a Splintering Cyberspace

In 2020, the pandemic accelerated digitalization around the globe. Homeoffice, Online Shopping, Zoom Conferences became part of the daily life for billions of people. But if somebody would have expected that the Covid-19-Desaster is a wake-up call for the world to be more united, work hand in hand, and pool resources reducing risks of a borderless threat, this "somebody" was wrong. 2020 was dominated by "My country first." more

Role Of The Government In The Internet Infrastructure Revisited

When thinking about the infrastructure of the Internet, it is important to consider the role of government in this infrastructure.

This is a question that involves two aspects: the role of government, and the role of the computer scientists who are part of the needed government structure or institution. Reviewing the history of the development of the Internet helps to highlight the importance of some role for both government and for computer scientists. more

IPv6 and Transitional Myths

I attended the RIPE 61 meeting this month, and, not unexpectedly for a group that has some interest in IP addresses, the topic of IPv4 address exhaustion, and the related topic of the transition of the network to IPv6 has captured a lot of attention throughout the meeting. One session I found particularly interesting was one on the transition to IPv6, where folk related their experiences and perspectives on the forthcoming transition to IPv6. I found the session interesting, as it exposed some commonly held beliefs about the transition to IPv6, so I'd like to share them here, and discuss a little about why I find them somewhat fanciful. more

Don’t Register Your Domain in the U.S. if it’s Controversial

In the news lately have been a number of incidents where U.S. courts, or the U.S. government itself has ordered domain registrars to shut down free speech. First was the E360 vs Spamhaus case, in which accused spammer E360 Insight sued anti-spam organization Spamhaus for labeling them as spammers and won by default when Spamhaus insisted that U.S. courts did not have jurisdiction over them in England and didn't appear. Unfortunately, U.S. courts did have jurisdiction over Spamhaus' domain registrar, who was nearly ordered to shut Spamhaus down (a court order was under consideration). Fortunately, Spamhaus was able to move their registration overseas before any shutdown order could be issued... more

Why Satellite Cellular Won’t Replace Traditional Cell Networks Anytime Soon

There was a burst of recent press about cellular service provided from satellites. This was probably prompted by the two recent hurricanes that have disabled terrestrial cellular and broadband networks in the southeast. I've seen speculation and discussion on Reddit and other forums where people have been wondering if satellite is the future of cell service and if the ubiquitous giant cell towers will eventually become obsolete. more

Internationalizing Top-Level Domain Names: Another Look

A paper by Dr. John C. Klensin, former Vice President of Internet Architecture at AT&T, a Distinguished Engineering Fellow at MCI WorldCom, and Principal Research Scientist at MIT. This paper has been reproduced with kind permission from the Internet Society. "Over the last few years, rising interest in internationalized domain names has been accompanied by interest in using those names at the top level and, in particular, replacing or supplementing country-code based domain names with names in the language of the relevant countries. This memo suggests that actually creating such names in the DNS is undesirable from both a user-interface and DNS management standpoint. It then proposes the alternative of translating the names so that every TLD name is available to users in their own languages." more

Do You Need a License to Look for Spam?

Jay Fink had an interesting little business. If you lived in California, you could give him access to your email account; he'd look through the spam folder for spam that appeared to violate the state anti-spam law and give you a spreadsheet and a file of PDFs. You could then sue the spammers, and if you won, you'd give Fink part of the money as his fee. more

More Top-Level Domain Wildcards

With all of the recent excitement about *.cm, the Cameroonian wildcard that someone is using to collect vast numbers of mistyped .com addresses, I wondered how many other wildcards there were at the DNS top level. There's a total of 13. Half of the wildcards are harmless. The *.museum wildcard leads to a registry page that helps guess what you might have been looking for. ...The .mp page also claims that .mp is for Mobile Phone rather than for the Marianas Islands, but they're hardly the only small poor island to try to cash in on their ccTLD, and they at least run it themselves. more

Innovation in DNS Business

One thing that amazed me about the ICANN community is the creativeness in finding new business models. I am not even talking about new technology like Internationalized Domain Names (IDN), the number of business models created from the vanilla DNS (actually just .com) are just mind boggling. ICANN was formed in 1999 and introduced the concept of registries and registrars model to the DNS business. With that, we witness the rise of register.com, an IPO darling in the dotcom days, in the early 2000s and subsequently overtaken by the ultra-cheap high-volume reseller model of GoDaddy. We also see new registries like .info and .biz and several others that didn't do so well. There are also after-market (aka ebay) for domain names like afternic and registry outsourcing, DNS hosting, Dynamic DNS etc. That's about what most outsiders know of DNS business models, mostly revolved around the registry-registrar-reseller model. But there are really more and I shall discuss two not-so-well-known but interesting models below. more
