Public DNS

Definitions

1. DNS resolution services offered for broad public use over the internet, such as Google's or Cloudflare's public recursive resolvers. Public DNS can improve reliability or privacy in some cases, but it can also bypass enterprise policy, monitoring, or internal naming assumptions.

   In plain English: DNS resolver services that anyone on the internet can use.

   Example: "The branch laptops were quietly using public DNS, which bypassed the corporate resolver's filtering and logging controls."
