ANNOUNCE: bgptables.merit.edu - understanding visibility of your prefix/AS

Fri Jan 13 20:19:04 UTC 2012

All,

We would like to announce the availability of the bgpTables Project at Merit at: http://bgptables.merit.edu
bgpTables allows users to easily navigate global routing table data collected via routviews.org.  bgptables
essentially processes the data collected at routeviews and makes is available in a somewhat easier
to use interface. The goal of bgpTables is to represent global prefix and AS visibility information from the
vantage point of the various bgp table views as seen at routeviews. 
The data is currently updated nightly (EST) but we hope to improve this over time. 
Please see the FAQ (http://bgptables.merit.edu/faq.php) for some simple examples of how you can use bgpTables.

Some examples:
- You can query for a specific ASN by entering the text 'as' followed by the AS number into the search box. For example to query for information about AS 237 you would enter 'as237' [without quotation marks] into the search box and then click 'search'. You can then use the view navigator map to switch to different routing table views for this ASN

- You can query for a specific prefix by directly entering the prefix into the search box. For example to query for information about prefix 12.0.0.0/8 you would simply enter '12.0.0.0/8' [without quotation marks] into the search box and then click 'search'. You can then use the view navigator map to switch to different routing table views for the prefix.

- You can find a particular prefix that you might be interested in by running a 'contained within' query via the search box. For example to quickly browse a list of prefixes contained within 1.0.0.0/8 to find the particular prefix you might be interested in, you can enter the text 'cw1.0.0.0/8' [without quotation marks] into the search box and click 'search'. You can then browse the resulting table to select the particular prefix you might be interested in.

- You can simply enter the text 'as' followed by the company name into the search box then click search to view a list of possible matches for that text. For example, to view all matching google ASNs you can simply enter 'asgoogle' into the search box and click search. A list of possible matching ASNs that reference Google by name will be returned from which you an then select the particular ASN that is of interest to you.

Comments, corrections, and suggestions are very welcome.  Please send them to mkarir at merit.edu.  Hopefully folks will find this useful.

Thanks.
