ip2host

Resolve IPs to hostnames in web server logs

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.
