+ 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.
