Lots of comments here about how IPs aren't PII b/c they can change, etc. I'm not arguing that, but consider that there is an entire _industry_ around using IPs to specifically target people, companies and households that is effective enough for businesses to write large checks to them.

Household IP Targeting - https://www.vicimediainc.com/ip-targeting-direct-mail-intern...

Or even just your ISP (who for sure know your IP addr and your address) - https://arstechnica.com/information-technology/2017/03/how-i...

The larger issue that we (HN tech people) treat IPs as fallible because we're thinking of it like an absolute. The advertising side of the Internet looks at them like a goldmine b/c even a 75% correlation to "truth" can still make their ads reach the people they're trying to reach in a much cheaper way.

I just signed up for the trial and Reveal turns up nothing on my home IP address.
