A Short History of DNS Over HTTP (So Far)

The IETF is in the midst of a vigorous debate about DNS over HTTP or DNS over HTTPS, abbreviated as DoH. How did we get there, and where do we go from here? (This is somewhat simplified, but I think the essential chronology is right.) Javascript code running in a web browser can't do DNS lookups, other than with browser.dns.resolv() to fetch an A record, or implicitly by fetching a URL which looks up a DNS A or AAAA record for the domain in the URL. more

A Quick Look at QUIC

Quick UDP Internet Connection (QUIC) is a network protocol initially developed and deployed by Google, and now being standardized in the Internet Engineering Task Force. In this article we'll take a quick tour of QUIC, looking at what goals influenced its design, and what implications QUIC might have on the overall architecture of the Internet Protocol. more

What Is the Most Secure VPN Protocol?

VPN products vary greatly in convenience, efficiency, and security. If security is a serious concern, an organization needs to pay close attention to the protocols a service supports. Some widely used protocols have significant weaknesses, while others offer state-of-the-art security. The best of the lot today include OpenVPN and IKEv2. What's called a VPN protocol is actually a collection of protocols. There are several functions which every VPN has to manage. more

Creating TLS: The Pioneering Role of Ruth Nelson

As often occurs in networking and cryptographic history, anecdotes and insularity conspire to mask how developments actually occurred, and seminal roles undertaken by women are forgotten or ignored. One of the notable examples of this proclivity occurred in the cybersecurity cryptology arena as it involves a critical platform known as the Transport Layer Security Protocol (TLS) and the pioneering role of Ruth Nelson. more

New Report About Internet Routing With MANRS

I find myself reading, frequently, about "interesting" exploits of IP routing. Recent history includes the redirection of Telegram traffic to Iran, Google traffic to China, and Cloudflare traffic to Nigeria -- and, per bgpstream.com, 64 events this month, 18 of them on one day. Is this expensive? You bet, both in money and in mindshare. Imagine the impact of discovering your company's name in the press. more

Join the Quantum Internet Hackathon 2018

The eighth RIPE NCC hackathon takes on the Quantum Internet! The hackathon will be held during the weekend before RIPE 77 in Amsterdam, and is co-organised by QuTech and TU Delft, along with the RIPE NCC. We're bringing together network operators, quantum networking researchers, students, hackers, software developers and artists, to imagine and build the tools for the future Internet. more

An Update on Securing BGP from IETF 102

One way or another we've been working on various aspects of securing the Internet's inter-domain routing system for many years. I recall presentations dating back to the late '90's that point vaguely to using some form of a digital signature on BGP updates that would allow a BGP speaker to assure themselves as to the veracity of a route advertisement. more

Addressing Technical and Operational Needs with TechOps

In the ICANN realm, TechOps stands for Technical and Operations and its goal is to simplify processes, to find solutions, and to advise on technical and operational matters. There are three TechOps groups: The Registry, the Registrar and the joint Registry and Registrar, also known as Contracted Party House (CPH). How did we get there and what exactly are we doing? more

Internet Evolution: Another 10 Years Later

Ten years ago, I wrote an article that looked back on the developments within the Internet over the period from 1998 to 2008. Well, another ten years have gone by, and it's a good opportunity to take a little time once more to muse over what's new, what's old and what's been forgotten in another decade of the Internet's evolution... The evolutionary path of any technology can often take strange and unanticipated turns and twists. more
