Ask HN: How does Clearbit Reveal know who I am?
When I visit https://clearbit.com/reveal there is a screenshot of a web page. I've visited the page a few times from my home internet connection, and the image has been either:
A) My personal blog (on my own domain)
B) My company's web site
It's pretty impressive (or creepy, depending on your viewpoint) that they can map my IP address to a company and/or individual identity.
I'm curious about how they do it. I have some ideas, but nothing that would explain it working so well. Maybe I entered my email address on a form on a site that shares data with Clearbit, but wouldn't my IP address change often enough that this wouldn't be useful for more than a couple of days?
Anyone else have any ideas?
- sergiotapia 6y agoeven with ublock origin it showed my company's website. how?
- Nextgrid 6y agoWhere does it show that? Am I missing something? On my side it shows Segment's website in the two screenshots, I am not sure if this is just an example or if it believes I am linked to Segment in some way?
- rahimnathwani 6y agoIt shows segment as a fallback if it has no data on you.
- whalesalad 6y ago> wouldn't my IP address change often enough that this wouldn't be useful for more than a couple of days? Yes, that’s right. But your IP and all the other little atoms of data that are collected on you by various third parties are traded back and forth to form a rich web. Over time the value of any given data point (like your ephemeral DHCP lease) becomes less significant to the integrity of the picture that has been created of you.
- codegladiator 6y agonot sure what you are talking about. it shows me couple of random websites which i have never visited (eg asana ? and selseforce twice this day ?) which makes no sense or atleast completely random to entice the visitor
