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

Wed Jan 18 14:22:46 UTC 2012

	For example for any given prefix to get which ASNs have originated that prefix over time and when.

	I think that could be interesting for discovering if a prefix has been hijacked in the past.

	RIS from RIPE NCC provides something like this:

http://www.ripe.net/data-tools/stats/ris/routing-information-service

	We have used it to verify some "suspicious" announcements of prefixes.

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.

>>> - 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.
