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

Mon Jan 16 20:44:08 UTC 2012

Please remember to add the "as" before the number for your query.
so for AS 65000 your search term should be "as65000"

Thanks.

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

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.

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.

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.
