Webalizer with Autonomous System Numbers
Posted by Daniel Butler Thu, 03 Aug 2006 14:01:00 GMT
While researching web site statistics packages, I came across Webalizer-ASN, which identifies the Autonomous System a host belongs to.
Init Seven AG has developed an extension of The Webalizer called ‘webalizer-asn’, that supports AS number (Autonomous System Number) lookups to generate additional statistics based on the origin of the hosts that have visited a website.
The AS number identifies the AS (Autonomous System) a host is belonging to. An Autonomous System is a group of IP networks operated by one or more network operator/s which has a single and clearly defined external routing policy. (See RFC1930 for more information about AS numbers.)
It is useful for high-traffic sites and ISPs when they know from which networks the visitors are coming from. For example they can plan future peerings or other things based on this information.

Another interesting Webalizer derivative is AWFFull - A Webalizer Fork, Full o’ Features!, which adds, among other features, more than 12 months of history and CSS-styling for the reports.
