DNS Wars

The North American Network Operators' Group (NANOG) is now quite an institution for the Internet, particularly in the North American Internet community. It was an offshoot of the Regional Techs meetings, which were part of the National Science Foundation Network (NSFNET) framework of the late 80s and early 90s. NANOG has thrived since then and is certainly one of the major network operational forums in today's Internet – if not the preeminent forum for network operators for the entire Internet. more

Doing Our Part for a Safer, Stronger DNS

Public Interest Registry is the industry leader of DNS Anti-Abuse efforts on the Internet. Since our inception, we have worked to empower people and organizations that use the Internet to make the world a better place. Whether a .ORG is the foundation of an individual voice, a global non-profit, or any organization that is part of the mission-driven .ORG community, we are proud to have earned the trust of so many dedicated users. more

Cybercriminals Benefitting from Stalled Privacy/Proxy Policy

We've seen alarmingly BIG increases in multiple abusive behaviors – like phishing, hacking and malware – that often leverage the domain name system (DNS) and privacy/proxy services. Cybercriminals capitalize on gaps in DNS security measures, and ICANN is holding the door open for them by failing to implement their privacy/proxy policy. If you are ever targeted, you are not alone. more

The End of the Road: ICANN, Whois, and Regulation

There's a well-documented crisis facing the domain name system: very few who rely on domain name registration data from the Whois database to perform vital functions can do so any longer, which is escalating consumer harm and abuse on the internet worldwide. And the problems, thanks to ICANN's overly restrictive policy post-GDPR and a failing policy process, are piling up. more

Call for Participation – ICANN DNSSEC and Security Workshop at ICANN66, Montreal, Canada

The ICANN Security and Stability Advisory Committee (SSAC) and the Internet Society Deploy360 Programme are planning a DNSSEC and Security Workshop on Wednesday, 06 November 2019, during the ICANN66 meeting held from 02-07 November 2019 in Montreal, Canada. The original DNSSEC Workshop has been a part of ICANN meetings for many years and has provided a forum for both experienced and new people to meet, present and discuss current and future DNSSEC deployments. more

Domain Name System to Be Featured Prominently in Upcoming Review of EU Safe Harbor Rules

In July 2019, Netzpolitik and others leaked an internal document by DG Connect that outlines the European Commission's thoughts on an update of the E-Commerce Directive. Based on this document, it seems that the domain name system and its actors will be prominently addressed in the Ursula von der Leyen's Commission-cycle from 2019 to 2025. more

DoH Creates More Problems Than It Solves

Unlike most new IETF standards, DNS over HTTPS has been a magnet for controversy since the DoH working group was chartered on 2017. The proposed standard was intended to improve the performance of address resolutions while also improving their privacy and integrity, but it's unclear that it accomplishes these goals. On the performance front, testing indicates DoH is faster than one of the alternatives, DNS over TLS (DoT). more

DNS-over-HTTPS: Privacy and Security Concerns

The design of DNS included an important architectural decision: the transport protocol used is user datagram protocol (UDP). Unlike transmission control protocol (TCP), UDP is connectionless, stateless, and lightweight. In contrast, TCP needs to establish connections between end systems and guarantees packet ordering and delivery. DNS handles the packet delivery reliability aspect internally and avoids all of the overhead of TCP. There are two problems this introduces. more

DoT and DoH Guidance: Provisioning Resolvers

As part of a larger effort to make the internet more private, the IETF defined two protocols to encrypt DNS queries between clients (stub resolvers) and resolvers: DNS over TLS in RFC 7858 (DoT) and DNS over HTTPS in RFC 8484 (DoH). As with all new internet protocols, DoT and DoH will continue to evolve as deployment experience is gained, and they're applied to more use cases. more

The Promise of Multi-Signer DNSSEC

DNSSEC is increasingly adopted by organizations to protect DNS data and prevent DNS attacks like DNS spoofing and DNS cache poisoning. At the same time, more DNS deployments are using proprietary DNS features like geo-routing or load balancing, which require special configuration to support using DNSSEC. When these requirements intersect with multiple DNS providers, the system breaks down. more
