-Technical note
+Forthcoming:
- adns requires a real nameserver like [2]BIND or [3]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.
-
+ 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'
+ queries through a single query socket.
+ * IPv6 support.
+ * Some kind of awareness of DNSSEC.
+ * Possibly some very limited caching behaviour.
+ * There was, at one point, a draft native Perl interface from Tony
+ Finch.
+
Documentation
I'm afraid there is no manual yet. However, competent C programmers
- should be able to use the library based on the [4]commented adns.h
+ should be able to use the library based on the [2]commented adns.h
header file, and the usage messages for the programs should be

I have set up mailinglists adns-announce and adns-discuss. The
announcements list is moderated and will contain only announcements of
