per-Regional Internet Registry Basis. A detailed explanation of the daily routing report is now
Various presentations regarding summaries from the Routing Report
are located in the archive on this system.
Data Sources and Analysis Results
Analysis is carried out on the BGP data obtained from the APNIC router at
NSPIXP-2 (now DIX-IE). Since the
project started, analysis of the Route Views project hosted at the
University of Oregon was added.
Current data is available below. It is updated every day.
Historical data is also available below:
I would like to acknowledge and thank APNIC for kindly agreeing to host this website, for
providing this system to process and store the data, and for access to
their routers to get the BGP table.
