About:
adns is an advanced, easy-to-use asynchronous DNS resolver library for C and C++ programs. It provides a robust alternative to the standard synchronous resolver functions, allowing applications to perform non-blocking DNS lookups efficiently. The package also includes command-line utilities for performing DNS queries from the shell.

Key Features:

Asynchronous and non-blocking resolution
Simple C/C++ API for integration
Comprehensive command-line query tools
Supports both IPv4 and IPv6

Use Cases:

Building network-intensive applications requiring fast DNS lookups
Debugging DNS issues via command-line utilities
Replacing blocking system resolver calls in daemons

Alternatives:

c-ares – c-ares is another popular async DNS library, often used in major projects like cURL.
unbound – Unbound is a validating, recursive, and caching DNS resolver, often used as a local DNS server rather than a client library.
