How and Why To Re-Rout DNS Through Your Computer or Phone

In a few of my previous tutorials I briefly touch on DNS re-routing, but never really get into it in full details, so I figured why not here today? Before moving forward, learning to re-route your DNS is important because it is a means of protecting your personal data, devices, network connectivity and internet traffic away from the spying or prying eyes of your Internet Service Provider (ISP), Government and any other interested 3rd parties, such as advertisers or even hackers. As for how DNS works or how switching it effects your internet connectivity, I think the short video below is the best demonstration. It explains how DNS re-routing configures your computer or phone to connect through a DNS server first, in order to connect to a website second – instead of connecting to a server owned by your ISP to connect to that same website, get it?

While there are number of ways to re-route your DNS and different services providers to choose from, for the purposes of this article, I consider the following to be the worlds best “Top 3” – Cloudflare DNS, IBM Quad 9 and Google’s Public DNS. As you can read below, each of which have their own unique benefits.

Cloudflare DNS:

Ipv4: 1.1.1.1
Ipv6: 1.0.0.1
Ipv6: 2606:4700:4700::1111
Ipv6: 2606:4700:4700::1001

Cloudflare DNS is my personal DNS provider of choice, installed on both my computer and phone. As for why I choose them, this is because Cloudflare DNS anonymizes IP Addresses, deletes logs daily and doesn’t mine any user data. Additionally, Cloudlfare DNS also offers security features not available in many other public DNS service providers, such as “Query Name Minimization” – which diminishes privacy leakage by sending minimal query names to authoritative DNS servers when connecting to websites.

IBM Quad 9:

Ipv4: 9.9.9.9
Ipv4: 149.112.112.112
Ipv6: 2620:fe::fe
Ipv6: 2620:fe::9

IBM Quad 9. Whereas Cloudflare may be more beneficial for activists and researchers, IBM Quad 9 on the other hand is probably of more benefit to your average home owner, parent or business owner. This is because Quad 9 routes your internet connections through DNS servers that actively blacklist known malicious websites, as well as websites which have previously been compromised by data breaches. In addition to this, Quad 9 servers also protect your internet’s incoming/outgoing connections as a means of preventing any of your devices from being caught up in a botnet. Quite simply, this means that while on Quad 9 servers, you never have to worry about any of your devices being hijacked or caught up in any sort of DDoS or crypto-mining campaigns, even smart devices connected to the “Internet of Things” (IoT).

Google Public DNS:

Ipv4: 8.8.8.8
Ipv4: 8.8.4.4
Ipv6: 2001:4860:4860::8888
Ipv6: 2001:4860:4860::8844

Google Public DNS servers on the other hand are ideal for people in countries such as Ethiopia, Sudan, Turkey, Syria, North Korea and the like which are all known to have restricted, censored, shut down and/or sealed off access to certain portions of their national internet in the past. In fact, as you can see via the picture provided below, activists affiliated with Anonymous Cyber Guerrilla have literally spray painted Google’s 8.8.8.8 DNS in public places in times of National crises as a means of raising awareness and alerting citizens how to bypass local internet restrictions imposed by their Government – opening people back up to the global world-wide-web. In addition to bypassing regional internet restrictions, compared to ISP’s in some 3rd world regions, switching to Google DNS servers might actually help improve or speed up your load time/internet connection.

That’s it, really. Generally speaking, the setup should be the same on your Apple PC just as well. It’s also important to note that you can actually do a mix-match of the addresses listed above. For example, you can use Cloudflare for IPv4, but then choose IBM for IPv6 – vice versa – and your internet connection will not be broken. Just so you are aware, while IPv2 usually signifies the country of origin or device where you are coming from, but most all devices on the world-wide-web these days connect to websites via IPv4 connections, making IPv4 the most important settings to modify.

How To Switch DNS On Phone?

Changing or re-routing the DNS settings on your phone can either be incredibly complicated or incredibly simple, depending on your level of skill/expertise. However, far and away the easiest means to go about accomplishing this is by installing a 3rd party App – either by going to your App, Apple or Google Play store(s). Simply just type in “Change DNS” to your search settings, press enter, and this should open up a whole host of options to choose from. Simply choose the one that you feel is best for you and enter in the Addresses listed above.

If You are A Little More Advanced…

OpenNIC Project. For those of you whom may be unfamiliar, “OpenNIC (also referred to as the OpenNIC Project) is a user owned and controlled top-level Network Information Center offering a non-national alternative to traditional Top-Level Domain (TLD) registries; such as ICANN. Instead, OpenNIC only operates namespaces and namespaces the OpenNIC has peering agreements with.

In other words, they are open DNS addresses, servers and proxies not indexed by global internet agencies or their Governments. Stay classy mi amigos 😉
