While public DNS resolvers like Google or Cloudflare offer speed and convenience, they can also introduce risks. Your DNS queries may be logged, exposing browsing habits, and open resolvers are more vulnerable to attacks like DNS spoofing, cache poisoning, and DDoS disruptions. For sensitive environments, consider using a secure, private DNS resolver with DNSSEC and encrypted DNS protocols to keep your traffic safe and confidential.
