adns - advanced, alternative, asynchronous resolver

GNU adns

Advanced, easy to use, asynchronous-capable DNS client library and utilities.

adns is a resolver library for C (and C++) programs, and a collection of useful DNS resolver utilities.

C library

In contrast with the standard interfaces, gethostbyname et al and libresolv, it has the following features:

DNS utility programs

adns also comes with a number of utility programs for use from the command line and in scripts:


I'm afraid there is no manual yet. However, competent C programmers should be able to use the library based on the commented adns.h header file, and the usage messages for the programs should be sufficient.


I'd be pleased if you would let me know if you're using my library in your project, and what you think of it.

If you are subscribed to adns-discuss please send feedback, including bug reports, there; otherwise send mail to If you'd prefer that your message wasn't forwarded to the adns-bugreports list, send it to


I have set up mailinglists adns-announce and adns-discuss. The announcements list is moderated and will contain only announcements of important bugs, new versions, etc. The bug reports address mentioned above is also a mailing list; feel free to subscribe to it.

There are archives and subscription web pages, or you can subscribe by sending mail containing the word `subscribe' to or


Available for download from are: adns is also available from the GNU Project FTP servers and their mirrors.

Technical note

adns requires a real nameserver like BIND or Dents running on the same system or a nearby one, which must be willing to provide `recursive service'. I.e., adns is a `stub resolver'. All properly configured UN*X and GNU systems will already have such nameserver(s); they are usually listed in /etc/resolv.conf.
