adns is a resolver library for C (and C++) programs. In contrast with
the existing interfaces, gethostbyname et al and libresolv, it has the
several are available. It has sensible handling of bad responses
etc.
+ adns also comes with a number of utility programs for use from the
+ command line and in scripts:
+ * adnslogres is a much faster version of Apache's logresolv program.
+ * adnsresfilter is a filter which copies its input to its output,
+ replacing IP addresses by the corresponding names, without unduly
+ delaying the output. For example, you can usefully pipe the output
+ of netstat -n, tcpdump -ln, and the like, into it.
+ * adnshost is a general-purpose DNS lookup utility which can be used
+ easily in shell scripts to do simple lookups. In a more advanced
+ mode it can be used as a general-purpose DNS helper program for
+ scripting languages which can invoke and communicate with
+ subprocesses.

Forthcoming:
+ A native Perl interface is in the works, thanks to Tony Finch.

I hope that future versions may also have the following features:
* The library should be useable by threads in a multithreaded
program in a natural way. It should multiplex many threads'
I'm afraid there is no manual yet. However, competent C programmers
should be able to use the library based on the commented [3]adns.h
