1.1.1.1: Cloudflare's DNS Resolver

1.1.1.1 is Cloudflare's public DNS resolver, launched in 2018 with a focus on speed and privacy.

1.0.0.1 is its backup address; 1.1.1.2 and 1.1.1.3 offer malware and adult-content filtering.

1.1.1.1 belongs to APNIC, the Asia-Pacific address registry, which partnered with Cloudflare to run the resolver; for years the address was barely usable because so much misconfigured equipment sent junk traffic to it. Cloudflare commits to not selling query data and to deleting logs that identify users within 25 hours, audited by a third party.
