Private DNS server

A private DNS server resolves names for a private network or a defined set of clients. It can answer from internal zones, forward queries to another resolver, or apply organization-specific policy, but its privacy and security depend on the network and configuration around it.

Also known as private resolver.

Why it matters in practice

Private resolution helps services find internal resources without publishing every name in public DNS. Administrators need to consider who can query the server, which upstreams receive forwarded questions, and how records are maintained. Private DNS does not mean queries are automatically encrypted or individually authenticated.

Example

A service inside a test network asks its configured resolver for an internal service name that is not published in public DNS.
