Cloudflare Registrar: what happens when you register a domain?

Every website, large or small, started with an idea, rapidly followed by registering a domain. Most registrars offer promotions for your initial domain registration and then quietly hike the price with each renewal. What they don’t tell customers is that the price they pay to a registry, for your registration, is set by the registry. In some cases, we’ve found registrars charging eight times the wholesale price for a domain renewal.

Today, we’re launching Cloudflare Registrar, the first domain registrar you can love. Cloudflare Registrar will never charge you more than what we pay to the registry for your domain. No markup and no surprise fees. For eight years Cloudflare has built products that make the internet faster and safer. It's time for us to start where your internet journey starts, your domain.

A quick introduction to domain registration

When you register a domain, you become the owner, or registrant, for that domain for a set period of time. Now that you are the registrant, you can create an authoritative record that tells the world the nameservers for your domain. The domain name system, or DNS, uses those nameservers to direct traffic to the IP address of your server.

A Markdown-to-PDF Workflow on Linux

In May of last year I wrote about using a Makefile with Markdown documents, in which I described how I use make and a Makefile along with CLI tools like multimarkdown (the binary, not the format) and Pandoc. At that time, I’d figured out how to use combinations of the various CLI tools to create various formats from the source Markdown document. The one format I hadn’t gotten right at that time was PDF. Pandoc can create PDFs, but only if LaTeX is installed. This article describes a method I found that allows me to create PDFs from my Markdown documents without using LaTeX.

Two tools are involved in this new conversion process: Pandoc, which I’ve discussed on this site before; and wkhtmltopdf, a new tool I just recently discovered. Basically, I use Pandoc to go from Markdown (MultiMarkdown, specifically) to HTML, and then use wkhtmltopdf to generate a PDF file from the HTML.

The first step in the process is to use Pandoc to convert from Markdown to HTML, including the use of CSS to include custom formatting. The command looks something like this:

pandoc --from=markdown_mmd+yaml_metadata_block+smart --standalone \
--to=html -V css=/home/slowe/Documents/std-styles.css \
--output=<destination-html-filename> <source-md-filename>

This generates Continue reading

IoT roundup: Startups, big carriers flex their IoT muscles and California legislation

We’re back! Here’s the latest monthly roundup of big and not-so-big news in the world of IoT, ranging from carrier doings to a neat little startup. Buckle up.California legislates IoT security California’s state legislature this month sent a bill to Gov. Jerry Brown’s desk that would mandate the use of “reasonable” security features in any connected devices, which are defined as any device that “is equipped with a means for authentication outside a local area network.” So, essentially, anything that can be accessed via the Internet would be subject to SB 327.To read this article in full, please click here

Implications of Valley-Free Routing in Data Center Fabrics

As I explained in a previous blog post, most leaf-and-spine best-practices (as in: what to do if you have no clue) use BGP as the IGP routing protocol (regardless of whether it’s needed) with the same AS number shared across all spine switches to implement valley-free routing.

This design has an interesting consequence: when a link between a leaf and a spine switch fails, they can no longer communicate.

For example, when the link between L1 and C1 in the following diagram fails, there’s no connectivity between L1 and C1 as there’s no valley-free path between them.

Worth Reading: Are carriers still missing the IoT point?

Sprint is yet another operator to announce an IoT platform, but we still don’t have a real handle on what a really useful IoT platform would look like. So far, perhaps not surprisingly, what’s coming out focuses on what the operator does in the RAN to support IoT sensors. Is that all there is, or even the best overall place to focus? I don’t think so. —Tom Nolle @CIMI

Windows for Network Automation?

The OS landscape is changing and, yes, you can learn and run network automation tools on Windows.

After a hot, dry June day in Richmond I boarded an empty train. It being just myself and a couple opposite we struck up a conversation, awaiting the train’s departure. Over the next twenty minutes, as the train slowly worked through a procession of sun-baked stations, I discovered that my companions worked in IT, but in a much earlier time. The white-haired gent confessed to be a C programmer back in the 60s. We talked about software, home lab specs, and genial conversation flowed from mutual interests. However, when I idly announced ‘Microsoft have really changed, Windows has greatly improved’ the C gent gave my comments short shrift and cut them down with:

‘They can’t change, they’re too big.’

No matter, it was a serendipitous meeting that enriched a dull train journey.

That encounter stuck with me, especially the rejection of Microsoft, and I was reminded of it last week in a brief exchange with David Bombal on twitter. The #netdevops guys put together a video about using Windows as a developer environment and David mentioned some negative comments they had received Continue reading

5 criteria for application-aware SD-WANs

Over the past five years, SD-WANs deployments have skyrocketed. And for good reason: They increase network agility and cut the cost of network transport.One common myth about SD-WANs, however, is that they improve application performance. They certainly can under some circumstances, but there is no guarantee they will under all situations. SD-WANs address only part of the transformation of the network to becoming a digital enabler. SD-WANs must now become smarter, or “application aware,” to optimize user experience, improve customer service, and increase worker productivity. The requirement to have an application-aware network has never been more urgent, as application performance has a direct impact on a company’s top and bottom line. For example, according to an Accenture survey, 66 percent of millennials have changed their brand loyalties because of a bad user experience. Also, a recent ZK Research survey found that workers are 14 percent less productive than they could be as a result of poor application performance. Make no mistake; poorly performing applications are costing companies today.To read this article in full, please click here
