ip2host - 1.13-2.1 main

This script is a drop-in replacement for the logresolve.pl
script distributed with the Apache web server.
.
ip2host has the same basic design of forking children to handle
the DNS resolution in parallel, but multiplexes the communication
to minimize the impact of slow responses. This results in a
significant speed improvement (approximately 10x faster), and
the performance degrades more gracefully as the DNS timeout value
is increased.
