Yes, 1.1.1.1 is a completely legitimate public DNS service operated by Cloudflare, one of the largest internet infrastructure companies in the world. It was launched in 2018 as a fast, privacy-focused alternative to ISP-provided DNS servers. Cloudflare has published its privacy commitments publicly and hired an independent auditing firm, KPMG, to verify that it follows its stated policy of not selling user data or using DNS query data for advertising. The service is free, requires no account or software purchase, and is used by millions of people and organizations worldwide, including large enterprises. If you're worried about scams, the only real risk is mistyping the address, so always enter 1.1.1.1 directly rather than clicking links from unfamiliar sources.
