The Ghosts of Deletions Future – December 2018 Versus December 2019

In the absence of data on renewals and deletions which are yet to happen, it can be enlightening to compare the domain names from the zone files of a year ago to the domain names in the current zones. The first group is the legacy gTLDs. The "Retained" domain names are those still in the December 2019 zone files. The "Deleted" domain names are those which are no longer in the current zones. Some of the retained domain names may have been reregistered, but these are not renewals charts. more

LinkedIn Outage Due to DNS Issue

Users of LinkedIn were unable to access the site for several hours due to what the company has reported to have been a DNS issue. The site is claimed to have been accidentally pointed to a domain name parking page and some users were greeted with a domain for sale page when trying to access LinkedIn's homepage. According to downrightnow, LinkedIn's outage began around 6 pm PST on Wednesday and is continuing, though website has gradually resumed for some users. more

“In the Public Interest”

Prior to November 30th of this year, the National Telecommunications and Information Administration (NTIA) must decide whether to renew or allow to expire its Cooperative Agreement with Verisign, the private-sector corporation that operationally controls the root of the Internet.. The Cooperative Agreement is unusually obscure, especially considering its central role in the operation of the Internet's Domain Name System (DNS). more

Hilyard Has a Historic Chance to Activate ICANN At-Large

The .ORG sale has placed Maureen Hilyard – ICANN's At-large Chair – squarely between the largest outpouring of individual user sentiment that the Internet community has ever seen, and the people who can do something about it. For At-large, the stakes are high. ICANN has spent years building up a user organization to balance corporate and government interests. At-large could be a key bulwark against the capture of Internet resources by those with capital and political power. more

What’s in Your DNS Query?

Privacy problems are an area of wide concern for individual users of the Internet -- but what about network operators? Geoff Huston wrote an article earlier this year concerning privacy in DNS and the various attempts to make DNS private on the part of the IETF -- the result can be summarized with this long, but entertaining, quote. more

ccTLDs Might Be Property

The long-running saga of victims who are pursuing 'state sponsors of terrorism' via ICANN has taken yet another turn. Some time back the Plaintiffs in Rubin & ors -v- Islamic Republic of Iran & ors managed to obtain Writs of Attachment in the Federal court district in Washington (D.C.) courts ordering that the ccTLDs of those respective countries be seized in part-payment of the damages they are owed. ICANN, fairly predictably, became involved at this point. more

How to Evaluate Performance of a DNS Resolver

Ten years ago everyone evaluating DNS solutions was always concerned about performance. Broadband networks were getting faster, providers were serving more users, and web pages and applications increasingly stressed the DNS. Viruses were a factor too as they could rapidly become the straw that broke the camel's back of a large ISP's DNS servers. The last thing a provider needed was a bottleneck, so DNS resolution speed became more and more visible, and performance was everything. more

New Data on Domain Name Contact Availability and Privacy

Nearly 90% of the internet's generic top-level (gTLD) domain names do not have identifying contact information in the Registration Data Directory Services (RDDS) system, according to a report by Interisle Consulting Group. A key finding of the report is the rapid growth of registrar-provided proxy service offerings and the inclusion of these services for both new and existing registrations. more

DNSSEC Rally

In late August the White House mandated that all of the agencies in the US government have functioning DNSSEC capabilities deployed and operational by December 2009. I am suggesting here that we, as a community, commit to the same timetable. I call upon VeriSign and other registries to bring up DNSSEC support by January 2009. more

Security Through Obscurity as an Institution

One of my staff members pointed me to an article by Mikko Hyppönen in Foreign Policy. In this article Mikko argues that a new top level domain (TLD) like .bank for some reason would prevent on-line fraud, at least partially. Mikko seems to be arguing that with a dedicated TLD registry for financial institutions and a fee high enough to act as an entry barrier you would have a trustworthy bank domains that would be immune against today's phising attempts... more

Attacking DNS Abuse: The Next Amendments Needed

Abusive behavior that leverages the domain name system (DNS) continues to be a problem, with a reach that has been widely and credibly documented. There is little doubt that bad actors continue to use the DNS for nefarious and costly purposes. While the amendments made in 2024 to ICANN's Registry Agreement (RA) and Registrar Accreditation Agreement (RAA) were a step in the right direction, more advanced tools are needed to bring abuse rates down. more

Call for Participation – ICANN DNSSEC and Security Workshop for ICANN74 Policy Forum

Do you have information about DNS security or routing security that you would like to share with the global community? Have you developed a new tool or system in this area? Do you have results from a research project that you want to share with a technical community? If so, please consider submitting a proposal to the DNSSEC and Security workshop to be held at ICANN 74 in June 2022. more

Minimized DNS Resolution: Into the Penumbra

Over the past several years, domain name queries - a critical element of internet communication - have quietly become more secure, thanks, in large part, to a little-known set of technologies that are having a global impact. Verisign CTO Dr. Burt Kaliski covered these in a recent Internet Protocol Journal article, and I'm excited to share more about the role Verisign has performed in advancing this work and making one particular technology freely available worldwide. more

Doing More to Address Child Sexual Abuse Materials Online

For all of us at Public Interest Registry, working to remove child sexual abuse content from the Internet isn't just a part of our work; it's our moral duty. As stewards of the .ORG community, addressing the problem head on is the only option compatible with our values. Talking about Child Sexual Abuse Materials (CSAM) is challenging and uncomfortable. It's also far too important, and prevalent, of a problem to ignore. While it's impossible to know exact numbers, online CSAM is a major, rapidly growing crisis. more

Twitter’s t.co Domain Outage Caused by Human Error

Declan McCullagh reporting in CNET: "Twitter last year began to abbreviate all hyperlinks using its t.co domain name -- which had the side effect of introducing a central point of failure where none existed before. That failure happened last night [Sunday Oct 7] around 11:30 p.m. PT when t.co went offline, meaning millions of Twitter users received 'non-existent domain' errors when trying to follow links." more
