ip block history.

[Greg Whynott <Greg.Whynott () oicr on ca>]

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!
