AS Connectivity Lookup

["Radke, Justin" <jradke () canbytel com>]

How can I easily view the current peering relationship of a particular AS?
Assume the AS you are researching does not have a looking glass and you are
not going to do lookups from the top 10 providers route servers to get some
glimpse of their connectivity. In my particular search
bgplay.routeviews.org does
not have any information and as-rank.caida.org is out of date. In the past
there was a great website called webtrace.info but it is no longer online.

Any suggestions?
