how are platforms like reddit able to get complete list of mullvad IPs and other vpns but not residential proxies?
- stoniejohnson 2y agopeople use mullvad IPs maliciously -> those IPs end up on blocklists
- adamomada 2y agoIt’s an industry now e.g. https://ipinfo.io https://ipinfo.io
- spxneo 2y agodamn this is crazy, how did they even compile all the residential proxies im seeing it detect!!
- fragmede 2y agoNet flows. A residential proxy should have a residential amount of traffic coming from it. If one IP has 1000x the usual traffic one household could reasonably account for, then mark it as a residential proxy. It won't be 100% accurate, but it's sufficiently accurate for reddit to go on a blocking spree.
- utensil4778 2y agoHow does one even get access to that kind of information? Are ISPs just selling this stuff or what?
- reincoder 2y agoWe have 700 servers around the world and we run measurements over all of the usable internet space, including assigned IPv6 addresses. I highly recommend reading some of our blog posts and community posts. You can also checkout our IP data tags page: https://ipinfo.io/tags https://ipinfo.io/tags
- reincoder 2y agoOur detection model at ipinfo is largely based on behavior models of IP addresses. We have 700 servers around the world from which we run internet measurement, allowing us to reliably determine which IP addresses are VPNs or proxies. These measurements are largely ping/traceroute data, which enable us to estimate a number of different things most importantly IP location data. If you are interested in what kind of other information we can discover from our internet measurements, check out our tags page: https://ipinfo.io/tags https://ipinfo.io/tags
- lbhdc 2y agoI am not sure how they do it, but one option is setting some arbitrary threshold for number of devices fingerprinted on a single ip in a given period of time. Something like taking the average number of devices and denying access to ips that they detect ~3 sigma different devices from.
- jorams 2y agoWell I don't know how many IP addresses each of Mullvad's servers have, but they list a domain name, IPv4 and IPv6 address for all of them publicly[1]. [1]: https://mullvad.net/en/servers https://mullvad.net/en/servers
