It is incredibly frustrating to run an internet speed test, see blazing-fast download numbers, and then sit staring at a blank white screen waiting for a simple news article to load. If your connection is solid but your browsing feels sluggish, the culprit is almost certainly your Domain Name System (DNS).
What is a DNS?
Think of DNS as the internet’s phonebook. Computers only understand numbers (IP addresses like 192.0.2.1). Humans understand words (like youtube.com). When you type a website name into your browser, your device asks a DNS server to look up the corresponding IP address so it can connect.
By default, your Internet Service Provider (ISP) automatically assigns you to their own DNS servers. The problem? ISP servers are notoriously slow, poorly maintained, and prone to outages. If their “phonebook” takes a full second to flip the pages, your website takes a full second to start loading.
The fix: Switch to a public DNS
You can bypass your ISP entirely and use massive, hyper-optimized servers run by tech giants. The two most popular are:
- Cloudflare: 1.1.1.1 (Known for extreme speed and privacy).
- Google: 8.8.8.8 (Incredibly reliable).
How to change your DNS (Windows 11)
- Press the Windows key and open Settings.
- Click on Network & internet, then click on Wi-Fi (or Ethernet if plugged in).
- Click on your network name to open its properties.
- Scroll down to DNS server assignment and click Edit.
- Change it from Automatic to Manual, and turn on IPv4.
- In the Preferred DNS box, type 1.1.1.1. In the Alternate box, type 1.0.0.1. Click Save.
How to change your DNS (iPhone/iOS)
- Open Settings and tap Wi-Fi.
- Tap the small blue “i” icon next to your connected network.
- Scroll down and tap Configure DNS.
- Change it from Automatic to Manual.
- Delete the existing servers, tap Add Server, and type 1.1.1.1. Tap Save.
🔥 The privacy bonus
Speed isn’t the only reason to switch. Did you know that your ISP can see every single website lookup you make through their default DNS? Many ISPs actively log this data and sell it to advertising networks. By switching to a service like Cloudflare (1.1.1.1), which strictly deletes all lookup logs within 24 hours, you instantly add a massive layer of privacy to your daily browsing.
