I work for IPinfo. We do not provide reputation scoring, by the way. Reputation is such a subjective matter.

It would be easy for us to make a very quick sales if we start offering reputation scoring, but we, as a company, would rather support fraud detection, threat intelligence and bot detection services with raw data from us.

In fact, the 1400 servers we operate for internet measurement all have very sophisticated honeypots baked into them, but still, we have not productized that data. In our experience of the fast-moving world of IP addresses, reputation scoring, even with the best intentions, can introduce some downsides. We can do many things which will be better than most things out there, but we have to really balance the consequences of our product.
