Hello Manish

Nice work on bgptables.merit.edu


Couple of things:


   1. It doesn't recognizes individual IP directly but needs complete block
   in CIDR to get info about it like e.g search for 8.8.8.8 gives nothing but
   8.8.8.0/24 gives information about Google. It would be worth it to have
   it looking at block to which an IP belongs to.

   2. You might consider adding graphs on AS connections - those are best
   for easy & quick reading. Something like for Google (AS15169) -
   http://bgp.he.net/AS15169#_graph4



Nice work, keep it going!

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 () merit edu.  Hopefully folks will find this useful.

Thanks.
