DNS is the phonebook of the internet: every website visit starts with a lookup at your ISP's servers. Those are often slow, log happy and censor-able.
Updated August 09, 2026, after a fresh review, with updated visuals and links.
Switching to a public DNS (Cloudflare, Google) takes five minutes per device, speeds up browsing visibly on many networks, and adds real privacy benefits.
What you'll need
- Any device
- Five minutes
- One of these addresses: 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google)
Here's how it works
1. Understand what you're changing
DNS translates names (netflix.com) into IPs. Your ISP provides the translator by default, seeing every site you ask about. Public DNS providers translate faster and promise not to build a marketing profile from your queries. The internet works identically, just the phonebook changes hands.
2. Windows 11 path
Settings, Network and internet, WiFi (or Ethernet), your connection, DNS server assignment, Edit, Manual, IPv4 on. Preferred: 1.1.1.1, Alternate: 1.0.0.1. Set DNS over HTTPS if offered, encryption for the lookups themselves, then Save.
3. Android path
Settings, Network and internet, Private DNS, and enter the hostname: one.one.one.one (Cloudflare) or dns.google. The beauty: this one setting covers WiFi AND mobile data, phone-wide, no per network work.
4. iPhone and Mac path
iPhone: Settings, WiFi, your network, Configure DNS, Manual, add 1.1.1.1. Mac: System Settings, Network, your connection, Details, DNS tab, same numbers. (Unfortunately iOS sets this per WiFi network, repeat for the ones you use.)
5. The router option: fix the entire house
Router admin page, Internet or WAN settings, DNS fields, same addresses: every device at home inherits it automatically. Easiest for families, and each device can still override its own.
6. Verify the change lived
Search 'test my dns' or visit 1.1.1.1/help: the page confirms whether your lookups travel through Cloudflare. A working change shows immediately, a typo'd one breaks browsing within seconds, revert fixes instantly.
Pro tips without the attitude
- Cloudflare (1.1.1.1) for speed and privacy focus, Google (8.8.8.8) for proven reliability: both beat most ISP defaults and are free.
- The 1.1.1.1 app (WARP) adds lightweight VPN privacy beyond DNS if you want more, free tier generous.
- ISP hijacked DNS (error pages full of ads) dies with this change: your queries stop being a revenue stream.
