DNS itself is a standard, necessary part of how the internet works, and using it is not inherently risky. The concern isn't DNS as a concept, but how a specific lookup gets handled and whether it can be tampered with along the way. Two real risks are DNS spoofing and DNS hijacking, where an attacker feeds your device a false IP address so you land on a fake or malicious site instead of the real one, often without any obvious warning sign. To reduce this risk, look for DNS providers that support DNSSEC, a set of protections that verify DNS responses haven't been altered in transit. Choosing a reputable, established resolver, such as Cloudflare, Google, or Quad9, instead of an unverified server also lowers your exposure. Used with a trusted provider, DNS is a safe and essential part of everyday browsing.
