Well - for starters, if you get a prefix that was announced by ASN
xxxx from [timestamp] to [timestamp], went to ASN yyyy  on [timestamp]
etc.

Quite useful if you want to tie this into route leak, prefix hijack,
malicious ASN etc tracking tools.

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 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.

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.
