How to speed up your internet and stop your ISP tracking you

Your entire DNS browsing history can be recorded by your ISP, and will soon be sold to anyone who wants it.

DNS is what sends you to the correct site when you browse the internet, but it is also non-encrypted, and reveals your entire browsing history. Your browser’s private mode does nothing, and the little green lock icon that denotes a secure connection doesn’t help either.

DNS is also slow. So, in order to fix both of these problems, you need to change your DNS provider to one that is both private, and fast. That’s Cloudflare’s new service.

What is DNS?

When you type something like Cult of Mac into your browser, a computer somewhere (usually your internet provider) looks up the actual IP address of that site. The common analogy is that of a phone book, which would be good if anyone under 30 knew what a phone book was. This all happens before you connect to the actual website you requested. DNS lookup happens every time you click a link to site, not just when you type a URL into your browser. There are a few problems with DNS:

  • It’s slow. Often your ISP treats your DNS like it treats the router it provides you — as a cheap afterthought.
  • It’s completely non-private. Your ISP knows every site you visit.
  • It’s spoofable. A dodgy DNS service can redirect you to spoof sites. A fake banking site, for example.
  • It can be used for censorship. A country can take control of DNS and use it to block certain sites.

Cloudflare DNS

Cloudflare is a content-delivery and DNS company, and it now offers a privacy-focussed DNS service. You should definitely check it out to see if you trust it with your data, but to be honest it can’t really be much worse than your ISP, can it?

Cloudflare’s new DNS service is a drop-in replacement for your current DNS provider (your ISP, almost certainly), and it offers the following advantages:

  • Privacy. Cloudflare promises not to log your IP address, and retains an external auditor to prove it.
  • Speed. The service seems to be quite a bit faster than even Google’s DNS service.

Even if you don’t care for the privacy angle, then you surely want faster internet, instantly, and for free, right?

How to use a new DNS server on Mac

To tell your Mac to use a different DNS server, you just have to give it the address. In this case, the address is

Go to System Preferences, and click on the Network panel. Then click on Wi-Fi (if that’s how you usually get on the internet), and click Advanced.

In the Advanced section, you should click on the DNS tab. This is where you type in the new DNS address. Just click on the + button, and type in Then clock the + button again, and type in the backup server address,

Just click OK, then Apply back on the main Network Settings page, and you’re done. From now on, all your internet activity will be routed through Cloudflare’s DNS servers.

The principle on the iPhone and iPad is the same. Go to Settings > Wi-Fi, and tap on the ⓘ next to the name of your home Wi-Fi network. On this page, you’ll see a button to Configure DNS. Then, ion the resulting screen, tap the + Add Server button, and type in your numbers:, and Remember to tap Save, and you’re done.

Other setups

There are two more things you should know. One is that you can’t change the settings for your cellular DNS server on iOS. That means that you can only use the Cloudflare (or other) DNS on a Wi-Fi or Ethernet connection.

The other is that it’s possible to set your home Wi-Fi router to use a custom DNS server, so that every device on your home network uses is automatically.

Now, then, you have a faster, more private connection to the internet, for free, and with minimal effort.
