## Projektgeschichte und Nutzung

GNU adns is Ian Jackson's asynchronous-capable DNS resolver library for C and C++ programs, accompanied by command-line resolver utilities. It offers a nonblocking resolver API and utility programs such as adnshost, adnslogres, and adnsresfilter.

### Projektgeschichte

The official homepage describes adns as an advanced, easy-to-use DNS client library and utilities collection. It contrasts adns with gethostbyname and libresolv by emphasizing asynchronous operation, multiple simultaneous queries, decoded response structures, sanity checking, explicit resolver state, and conventional resolv.conf support.

The official previous-versions directory shows public release tarballs starting with adns 0.1 in April 1999, progressing through 1.0 in 2000, 1.5.x in the 2010s, and 1.6.x releases in the 2020s. The homepage also points to a master git repository browser and notes that adns is available from GNU Project FTP servers and mirrors.

### Adoptionsgeschichte

adns became a GNU-distributed resolver component with both library and scriptable CLI use cases. The supplied package metadata shows broad packaging under Homebrew, Debian/Ubuntu adns-tools, Fedora/DNF, MacPorts, Nix, Arch/pacman, and openSUSE zypper.

The homepage lists ecosystem bindings and integrations, including Python bindings, liboop event-loop support, and an MS Visual Studio C++ port. That adoption pattern is very Unix-library-like: one C API, a few small command-line tools, and integrations by event loops and language bindings.

### Wie es verwendet wird

C and C++ programs use adns when they need DNS lookups without blocking on one resolver call at a time. The library can process many queries simultaneously, return decoded records, distinguish failure causes, and use or override conventional resolver configuration.

Shell and scripting users get adnshost for DNS lookups, adnslogres as a faster Apache logresolv-style tool, and adnsresfilter for replacing IP addresses in streamed command output without delaying the stream unnecessarily.

### Warum Paket-Nerds sich dafür interessieren

adns is package-nerd interesting because it is a classic Unix networking library packaged alongside small utilities, with GNU distribution, long-running release tarballs, and distro-specific binary splits. It also documents the resolver boundary clearly: it is a stub resolver and expects a real recursive nameserver on the same system or a secure nearby network.

### Zeitleiste

- 1999-04: adns 0.1 tarball appears in the official previous-versions directory.
- 2000-09: adns 1.0 tarball appears in the official previous-versions directory.
- 2014-11: adns 1.5.0 tarball appears after the long 1.4 era.
- 2020-06: adns 1.6.0 tarball appears.
- 2026-05: adns 1.6.2 tarball appears in the official previous-versions directory.
