probably an odd question …
we have been assigned a few large blocks of IPs, and while configuring BGP i got to wondering what these block's history might be. who had them in the past, etc..
is there a publicly accessible db or similar which tracks that type of information, or is that liability concern?
thanks! greg

assuming the whois data has been cleaned up the next resource to look at is: routeviews or ris table dumps to see where or if it was advertised in the past, and from where. google and rbl lists are also worth querying in that context. joel On 9/14/10 1:51 PM, Greg Whynott wrote:
