DNS resolver

A DNS resolver answers queries that map domain names to DNS records. A recursive resolver obtains or retrieves an answer for a client, often using caches and queries to other DNS servers; a stub resolver usually sends requests to a recursive resolver.

Also known as recursive resolver.

Why it matters in practice

The resolver is a key point in name lookup, but it does not see every detail of an application connection. Standard DNS on port 53 is not inherently encrypted, and a client’s query may still reveal the requested name to the resolver. In Hyperproxy, Pro+ DNS authentication applies to management API calls, not each port 53 lookup.

Example

A client asks its recursive resolver for the address records associated with api.example.com and then opens a connection using the returned data.
