1: What is bgpTables?

bgpTables allows users to easily navigate routing table data collected via routviews.org. The goal of bgpTables is to present global prefix and AS visibility information in an easy to use interface. All the information that is presented is extracted primarily from public information advertised via BGP routing tables.


2: How do I navigate the global map view selector?

The global map has been colored to roughly approximate RIR regions of the Internet. Clicking on a region will display the list of routing table view that are available for that region. You can then select the particular view you are interested in. For information across all views you can select the 'All Data' option on the map.


3: How do I view information for a given ASN?

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


4: How do I view information for a given prefix?

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.


5: I dont know the exact prefix but it is contained within x.x.0.0/16?

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.


6: I dont know the AS number that I am interested but I know it probably belongs to xyz? How can I find out ASN information using bgpTables?

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.
