Report Sections:

Status Summary

Summary of total route table size for the past 7 days and summary information on ASes.

Last Week's Changes

A summary of the last week's changes in terms of withdrawn and added routes and added ASes.

More Specifics

A list of ASes advertising routes that appear to be more specfic than the original Class-based prefix mask, or more specific than the registry allocation size.

Possible Bogons

A list of advertisements of address blocks and Autonomous System numbers where there is no matching allocation data.

This report is generated from an analysis of the BGP routing table withinRouteViews, and was produced at Tue Sep 17 14:25:14 2024 AEST.
