The Evolution of DNS: Adapting to the Changing Internet Landscape

The DNS is a crucial part of today's Internet. With the fracturing of the network's address space as a byproduct of IPv4 address run down and the protracted IPv6 transition the Internet's name space is now the defining attribute of the Internet that makes it one network. However, the DNS is not a rigid and unchanging technology. It has changed considerably over the lifetime of the Internet and here I'd like to look at what's changed and what's remained the same. more

Commercial DNSSEC?

Seems that DNSSEC is being subjected to what an old boss of mine used to call the "fatal flaw seeking missiles" which try to explain the technical reasons that DNSSEC is not being implemented. First it was zone walking, then the complexity of Proof of Non-Existence (PNE), next week ... one shudders to think. While there is still some modest technical work outstanding on DNSSEC, NSEC3 and the mechanics of key rollover being examples, that work, of itself, does not explain the stunning lack of implementation or aggressive planning being undertaken within the DNS community. more

DNSSEC: Will Microsoft Have Enough Time?

I have previously pointed out the shortcomings of good and user friendly support for DNSSEC in Microsoft's Server 2008 R2. During the period just after I wrote the post, I had a dialogue with Microsoft, but during the last months there has been no word at all. The reason I bring this up again is that more and more Top Level Domains (TLDs) now enable DNSSEC and also the fact that within six months the root will be signed. more

Mitigating DNS Abuse and Safeguarding the Internet

The internet is a beacon of global connectivity and information, but it has also become a battleground where malicious actors exploit vulnerabilities for various immoral purposes. Domain Name System (DNS) abuse stands has proven a constant in the internet threat landscape, posing risk to the overall digital trust. more

What Is the Domain Name Expiry Cycle and Why Should You Know About It?

Domain names are registered by the thousands every day. In July 2021, 236,336 domains were newly registered daily on average across all top-level domains (TLDs). Tens of thousands were also newly expired. Other months could be just as busy. "Newly registered" and "newly expired." Those are two terms I often get questions about. Newly registered domains are domains that someone just reserved, typically through a registrar or web hosting company. Newly expired domains, meanwhile, are those domains that someone had reserved but decided to let go for one reason or another. more

NIS 2.0 and Its Impact on the Domain Name Ecosystem

I recently appeared on the 419 Consulting podcast to discuss the European Union's NIS 2.0 Directive and its impact on the domain name ecosystem. I encourage all TLD registries, domain name registration service providers, and DNS operators to listen to the recording of that session which Andrew Campling has made available. more

DNSSEC Deployment at the Root

The DNSSEC is a security protocol for providing cryptographic assurance (i.e. using the public key cryptography digital signature technology) to the data retrieved from the DNS distributed database (RFC4033). DNSSEC deployment at the root is said to be subject to politics, but there is seldom detailed discussion about this "DNS root signing" politics. Actually, DNSSEC deployment requires more than signing the DNS root zone data; it also involves secure delegations from the root to the TLDs, and DNSSEC deployment by TLD administrations (I omit other participants involvement as my focus is policy around the DNS root). There is a dose of naivety in the idea of detailing the political aspects of the DNS root, but I volunteer! My perspective is an interested observer. more

Paul Vixie on How the Openness of the Internet Is Poisoning Us

In a video interview conducted during the NSCS ONE conference, Paul Vixie CEO of Farsight Security further discusses the topic of his presentation titled: "Defective by Design -- How the Internet's Openness is Slowly Poisoning Us". more

A Call to Help Disrupt the Spread of Child Sexual Abuse Materials

The Internet Watch Foundation (IWF) leads the charge to combat child sexual abuse material (CSAM) online, and we at Public Interest Registry (PIR) are dedicated to supporting their efforts. We are honored to work with them across two important programs: Domain Alerts and TLD Hopping List. IWF services have been extremely successful in addressing CSAM on .ORG over the past five years more

The Christmas Goat and IPv6 (Year 2)

Last year the municipality of Gavle asked my company if we could help them load share the streaming pictures of the famous Christmas goat in Gävle. I accepted the invitation and set up a separate domain. My own interest in this was of course to track the usage of IPv6 and validation of DNSSEC from the visitors of the site. more

DDOS and the DNS

The Mirai DDOS attack happened just over a year ago, on the 21st October 2016. The attack was certainly a major landmark regarding the sorry history of "landmark" DDOS attacks on the Internet. It's up there with the Morris Worm of 1988, Slammer of 2002, Sapphine/Slammer of 2009 and of course Conficker in 2008. What made the Mirai attack so special? more

The Ever-Evolving Problem of DNS Abuse

For several years, many within ICANN circles have raised concerns about the escalating nature of domain name system (DNS) abuse. While some strides were made toward a safer DNS, new data - this time from a comprehensive study of DNS abuse by the European Union - demonstrates that abuse remains a frustratingly obstinate problem that requires urgent attention. We've seen some registries and registrars testing innovative industry-led initiatives in an effort to address the issues. more

Vendor Selection Matters in the Domain Registrar Ecosystem

Domain name abuse is one of the most dangerous and under-regulated issues in digital business security today. Many of the largest companies in the world still lack basic domain security protocols, making them prime targets for bad actors. An attack on a domain can lead to the redirection of a company's website, domain spoofing, domain and domain name system (DNS) hijacking attacks, phishing attacks, network breaches, and business email compromise (BEC). more

DNSSEC Now Deployed in all Generic Top-Level Domains, Says ICANN

The Internet Corporation for Assigned Names and Numbers organization (ICANN org) announced that all of the current 1,195 generic top-level domains (gTLDs) have deployed Domain Name System Security Extensions (DNSSEC). more

Verisign Will Help Strengthen Security With DNSSEC Algorithm Update

As part of Verisign's ongoing effort to make global internet infrastructure more secure, stable, and resilient, we will soon make an important technology update to how we protect the top-level domains (TLDs) we operate. The vast majority of internet users won't notice any difference, but the update will support enhanced security for several Verisign-operated TLDs and pave the way for broader adoption and the next era of Domain Name System (DNS) security measures. more
