ip2host | Resolve IPs to hostnames in web server logs | Mehr ...
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.
