Google Public DNS is a free global DNS resolution service from Google. By default, our devices use default DNS resolution service provided by ISPs to connect to the internet.
What is DNS?
DNS stands for Domain Name System. It is a part of internet infrastructure which keeps records of domains and their IP addresses. Every time you visit a website, your computer performs a DNS lookup. This is where DNS servers tell your computer to connect to a certain IP address.
Advantages of Google Public DNS:
- Better performance with low latency
- Faster DNS resolution with adequately provisioned servers to handle huge traffic
- Prevents DoS and amplification attacks
- Global coverage
- implements DNSSEC, DNS-over-HTTPS
- Privacy: Google logs IPs temporarily for 24-48 hours. Other information logged for debugging are unidentifiable.
