Off topic but "Strava’s corporate IP address" - How do people even figure that out? Maybe it's super obvious, but I'm not familiar? Can someone explain...

Creator of Footpath here. I didn't know this was possible either until I looked up the suspicious IP from the logs: https://www.ip2location.com/demo/12.131.20.242

I ask this sincerely: how much understanding of internet protocols did you have going into this project?

whois <ip address> will show you the owner of an IP.

Sometimes it'll trace back just to an ISP, or to something like AWS, but larger companies will often own their own block of IPs directly.

Ahhh, I guess that's why I got confused. Anytime I had run an IP check at previous/current jobs, I would always get back a generic ISP so you wouldn't see the company name. I hadn't ever been at a job that actually had their own block of IPs like that. That's what tripped me up. Makes more sense. So basically you can sometimes get to that info of who it is, and sometimes not.
