help Google Public DNS Privacy Features FAQ

How long does Google Public DNS keep my IP address?

Google says temporary logs containing IP addresses and DNS query details are normally retained for 24 to 48 hours. They may be kept longer when needed to investigate security or abuse.

Does Google use Public DNS queries to target ads?

Google states that personal data from Public DNS is not used for ad targeting. It does retain permanent aggregate logs after removing or reducing identifying information such as full client IP addresses.

Does Google Public DNS support encrypted DNS?

Yes. Google Public DNS supports DNS-over-HTTPS and DNS-over-TLS, which encrypt queries between the device and Google's resolver.

Is using 8.8.8.8 enough to hide the websites I visit?

No. It changes the resolver handling DNS lookups, but it does not hide destination connections from websites, network operators, or other infrastructure, and ordinary unencrypted DNS can still be observed in transit.
