That system doesn't return information about the ISP: it returns
information about who the address block is registered to.
For example, if I enter one of my work IP addresses, then I
get information about the name of our organization, since that
particular block is registered to us. But that doesn't say anything
about who our ISP is. I don't even -know- who our ISP is these days,
as the local consortium contracts out ISP service on multiyear bids,
with no visible effect on our service.
