There Are at Least 10 Million DNS Resolvers on the Internet Today

In a blog post on the ICANN website, Joe Abley writes: "Resolvers are servers on the Internet which use the Domain Name System (DNS) protocol to retrieve information from authoritative servers and return answers to end-user applications... So, all in all, how many resolvers are there? Given that anybody can run one, it seems like a difficult thing to measure. It turns out, however, that all resolvers that talk directly to authoritative servers on the Internet leave a trail, and with a little data crunching we can come up with a number." more

DDoS Mitigation: A Blend of Art and Science

As DDoS attacks become larger, more frequent and complex, being able to stop them is a must. While doing this is part science, a matter of deploying technology, there is also an art to repelling sophisticated attacks. Arbor Networks, Citrix and others make great gear, but there's no magic box that will solve all your problems for you. Human expertise will always be a crucial ingredient. more

First .emarat Arabic Script Domain Name is Live!

The .emarat Arabic script Internationalised Domain Name (IDN) ccTLD for the United Arab Emirates has been entered into the DNS Root Zone and is therefore now resolving. This is a truly historic moment in the development of the Internet in the United Arab Emirates and the wider Arabic-speaking world as it removes the last hurdle preventing people without English-language skills from enjoying the full benefits that the Internet has to offer. more

The True Effect of Corona on the DNS

In recent weeks we've seen a range of press articles, security blogposts and public statements addressing real or perceived issues with network capacity and the domain name system (DNS) in particular. These range from concerns about the resilience of the DNS with questions on the impact of the number of registrations to news indicating that a tidal wave of fraud and abuse is hitting the world. more

ICANN at 20: Looking Back Forward

This year, the Internet Corporation for Assigned Names and Numbers (ICANN), marks its 20th anniversary since inception. ICANN was birthed as a result of the infamous DNS Wars - in 1994, the U.S National Science Foundation, the then overseer of the Internet infrastructure decided to sub-contract the management of the Domain Name System (DNS) to a private U.S company called Network Solutions INC (NSI). This move was not well received by the Internet community, culminating in the so-called "DNS Wars" more

ICANN Org’s Multifaceted Response to DNS Abuse

While the March report from ICANN's Domain Abuse Activity Reporting system show a general reduction in second-level gTLD domain names identified as being used in phishing, malware distribution, and botnet command and control, it has been widely reported that criminals are taking advantage of the global COVID-19 pandemic by launching malicious online campaigns. There have also been numerous reports of spikes in the use of COVID-19-related domain names for DNS Abuse. more

No External Attacks Behind GoDaddy’s Major Outage, Says Company

GoDaddy.com has reported today that the Web hosting outage that involved thousands and possibly millions of websites on Monday was due to internal issues and did not involve any attacks by hackers. The outage lasted for about four hours and affected mainly small-business sites. GoDaddy.com hosts more than 5 million websites. more

Welcome to Meltnet: A Blueprint for Digital Sovereignty in a Fragmented World

Meltnet envisions a federated internet model led by BRICS nations, combining digital sovereignty with cross-border interoperability. It challenges US-centric governance by proposing a trust-based architecture rooted in shared standards and mutual recognition. more

Study Finds Majority of U.S. Gov’t Agencies Fail to Meet Security Mandate for DNSSEC Adoption

Majority of U.S. Federal agencies using .gov domains have not signed their DNS with DNSSEC (Domain Name Security Extensions) despite a December 2009 Federal deadline for adoption, according to the latest report by IID (Internet Identity). IID analyzed the DNS of more than 2,900 .gov domains and has released the results in its "Q3 State of DNS Report". more

The Growth of DNS-OARC Highlights Great Strides in DNS Research

This past weekend several of my Dyn colleagues and I attended the DNS-OARC annual meeting and fall workshop in Montreal. "OARC" in the organization's title stands for "Operations, Analysis and Research Center". DNS-OARC was founded by the Internet Systems Consortium (best known as the maintainers of the BIND DNS software) in 2004 to address a gap in the DNS community. Engineers working to extend the DNS protocol itself have always had a home in the Internet Engineering Task Force (IETF), but there was no corresponding community for those who operated DNS infrastructure and did research using data gleaned from DNS operations. more

ICANN’s Ultimate Demise?

ICANN's proposed overhaul of root server governance would empower a new council to revoke America's operator status, risking a clash with a resurgent Trump administration and potentially imperiling the multistakeholder model that underpins the internet's core infrastructure. more

Want to Help Guide the Future of the MANRS Routing Security Initiative?

Would you like to help guide the future of the Mutually Agreed Norms for Routing Security (MANRS) initiative? As the MANRS community continues to develop new efforts to make the routing layer of the Internet more secure (ex. the equipment vendor program), would you like to help lead the work? The MANRS community is seeking volunteers for its new Steering Committee. The committee will lead the community as it evolves its governance model.  more

In AI, We Trust!?

When it comes to Artificial Intelligence (AI), there is a widespread fear that AI machines will "take over" and dominate humanity. Today, we should be concerned when governments and digital corporations use AI to replace trust as the fundamental value and principle in the digital domain. more

The Domain Name System: A Cryptographer’s Perspective

As one of the earliest protocols in the internet, the DNS emerged in an era in which today's global network was still an experiment. Security was not a primary consideration then, and the design of the DNS, like other parts of the internet of the day, did not have cryptography built in. Today, cryptography is part of almost every protocol, including the DNS. And from a cryptographer's perspective, as I described in my talk at last year's International Cryptographic Module Conference (ICMC20), there's so much more to the story than just encryption. more

AFRINIC Partners With ICANN on AFRICA DNS Business Exchange Programme

A series of internships have been set up to facilitate capacity building for registrars and registries in Africa to boost the African domain name business. Launched by ICANN in partnership with AFRINIC, the first phase of the DNS Business Exchange Programme involved interns selected from ICANN accredited registrars. more
