Bogon Report

This is a collection of report files that summarize the allocation status of the IPv4 address space and the Autonomous Number space.

The report is generated on a daily basis using the IANA registry files, the Regional Internet Registry stats files and the Regional Internet Registry whois data. The data sources and some commentary on this approach is summarized in a presentation pack.

This work has also generated some comments on the accuracy and consistency of the information provided in the IANA IPv4 address registry.
