dnshistory provides a means for storing a history of DNS/name changes over time from the IP Addresses gathered from within Web log files. At its simplest, it will do massively parallel name lookups very quickly. The lookups are not DNS only, and will use whatever naming services your system is configured with. A second mode will take a Web log file and replace the IP addresses with the previously stored names, sending the resulting output to STDOUT.
AWFFull is a Web server log analysis program, forked from Webalizer. It adds a number of new features and improvements, such as GeoIP capability, internationalisation, style changes via CSS, extended front page history (more than 12 months), resizable graphs, and lots of backend changes and simplification. The long term goal is to focus on Web Analytics, not just Web Reporting.
