The request names "DnsClient" but no specific product page describes a DNS client library by that name, so the closest matches are DNS resolver libraries: c-ares is a C asynchronous DNS stub resolver 8, and Hickory DNS provides stub resolvers and DNS libraries in Rust 5. Microsoft's DnsManagementClient is an Azure API client for managing DNS zones and records 4, which is a different job.

A question back: Did you mean a DNS resolver library for a specific language (e.g. Python, Rust, C) or a client for managing DNS records in a cloud provider?
