adns is a resolver library for C (and C++) programs, and a collection of useful DNS resolver utilities.
adnslogresis a much faster version of Apache's logresolv program.
adnsresfilteris 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.
adnshostis a general-purpose DNS lookup utility which can be used easily in from the command line and from 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. See the adnshost usage message for a summary of its capabilities.
