DNS (Domain Name System) is the internet's address book. Every time you type a URL, your computer queries a DNS server to find the matching IP address. A slow DNS means a slow web.
Why switch to Google DNS?
- 8.8.8.8 and 8.8.4.4 — among the fastest, most reliable DNS servers in the world
- DNS resolution time cut by 20 to 50% on average
- Better protection against DNS spoofing attacks
- Near-universal availability — 99.9% guaranteed uptime
