Subject: historic SWIP (or rwhois) data? 


I'm working on a forensics problem rather than a network operations issue. 

I've got a /28 that I can see is currently assigned to a certain company 
via rwhois. 

What I want to do is see this block's history over the last five years. It 
was involved in some problematic behavior back in 2012, I'd really like to 
know whose name was on it then. 

It would be ideal if this data were available in some sort of flat file 
format, or if a sensible API to it exists. 

I've been searching a little bit, just found this, not really seeing any 
place to download any of this data though.
