In May 2018, I posted this article: Speed up your browsing with CloudFlare’s public DNS
In that post, I recommended CloudFlare’s DNS, 184.108.40.206. At the time, it was quite fast, and worked perfectly.
Fast forward to today, and I’m afraid that’s no longer the case.
If you switched to CloudFlare’s DNS and you’ve noticed that things like paying via PayPal have become almost useless, read on!

Way back in 1995, I was a freshman at university. I had this new thing called “The Internet” at my fingertips.
It was cool, but I wanted to know how it worked. I asked someone, and they wouldn’t answer the question – mostly because they couldn’t answer!
Today, everyone knows and uses the internet, but people keep asking me questions about the basic concepts that make it go.
So, I figured it was about time to give a basic intro to how the internet actually works, including a simplified discussion of networks, IP addresses, ports, protocols, DNS, bandwidth, latency, and more!

Back on April 1st of this year, CloudFlare announced a new public DNS resolver service.
But in this case, it wasn’t an April Fool’s joke at all: the new 220.127.116.11 DNS service is very real and very fast!
Well, that’s nice, but what the heck does DNS do?
And how is it gonna make your web browsing speedier?

Whether it’s the “Iranian Cyber Army”, those darn “Chinese Hackers”, or just your average script kiddie, everyone is aware that there bad people out there who want to mess with your glorious internet surfing experience.
You probably have heard of things like DoS (Denial of Service) attacks, and you’ve most certainly heard about viruses, trojans, and worms. But there is one thing I’m betting you haven’t heard much about: DNS cache poisoning.
You’ll see why this is a very important type of attack to be aware of a bit later. First, I should probably cover a few basics in case you aren’t a techie nerd. Just for the record, nerds don’t wear coke bottle glasses anymore; they wear contacts. Junk food is out, and healthy eating is in. Flannel shirts? Yes. Pocket protectors? No. And contrary to popular belief, we are generally good-looking. It’s all part of Nerd 2.0.
But, I digress.
