Programs to get DNS and domain ownership information from web logs

Fastresolve is a package of programs to process web log files to get DNS and domain ownership information for log analysis. It sends out many queries in parallel, and caches results, for speed. Its DNS resolver is about 10 times as fast as logresolve.pl from the Apache 1.3.9 distribution, and about 50 times as fast as logresolve.c from that distribution. It is 5-20 times as fast as the adnslogres program that comes with the adns library, and about 3 times as fast as jdresolve, which is a Perl program that uses similar algorithms.
