BGP Routing Table Analysis


The Routing Report first saw light of day on the 23rd February 1999. The Internet was seeing explosive commercial growth then, and no one was paying any attention to what was happening on it. There were no published reports, and the CIDR Report was then used as a marketing tool by ISPs wishing to show off how "big" they were.

With the encouragement of APNIC and other colleagues in the industry, I started producing the daily Routing Report, taking a more detailed look at the state of the Internet Routing Table on a per-Regional Internet Registry Basis. A detailed explanation of the daily routing report is now available.

Various presentations regarding summaries from the Routing Report are located in the archive on this system.

Data Sources and Analysis Results

Analysis is carred out on the BGP data obtained from the APNIC router at DIX-IE (formerly NSP-IXP2). Since the project started, analysis of several other BGP feeds were started (some retired, some still running).

Current data are available below. It is updated every day between 4am and 9am +10GMT.

Historical data are also available below:

Note that the London data contain a dump of the IPv6 BGP table (with and without Team Cymru Bogon feed) - simply navigate to the 0700 folder in the daily data.

Historical data from reports no longer running:

Also some nice visualisations of the Internet (courtesy of Dean Pemberton and others) at these links:


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.
