Hi Siva,

I posted this to nanog for comment. There seemed to be consensus that this
is scaremongering.  this was probably the best response:

> The author has drawn a relationship between a lot of unrelated things.
> Hackers and spammers "rent" IP addresses all the time, and have done
> so for two decades. It's called, "Here's my money for colo hosting
> service and I need some IP addresses to go along with it." Nothing has
> changed as a result of IPv4 depletion.
> Botnets are hacked machines. They come with their own IP addresses
> scattered about the globe and don't require any particular source. No
> relation to IPv4 depletion and only tangentially related to the
> "bulletproof hosting" that supplies IP addresses for the C&C servers.
> As for auctioning IP blocks, my experience is that hackers don't
> bother. If they want IP addresses beyond what the colo provider
> offers, they steal them: find a block of addresses not routed on the
> public Internet and forge LoAs they present to their ISP. They're
> going to lose them anyway, so why bother paying money?
> Regards,
> Bill Herrin
