IP reputation check

Whether an IP looks like an ordinary person's connection, or like a proxy, VPN, Tor exit, datacenter server or known source of abuse. Websites use these signals to decide whether to show a captcha, ask for verification, or block a sign-up, login or payment.

It starts at 100 and loses points for each risk found. How many depends on how solid the evidence is: the more sources agree, the bigger the deduction. Tor exit node −60, proxy or VPN −30 to −46, datacenter IP −21 to −35, blocklists −6 to −30 (more lists cost more), blocklisted IPs in the same /24 −1 to −8 or elsewhere in the network −1 to −5, mobile network −2 to −6. Each risk counts once, and the breakdown under the score shows every point taken off. 80 and above is clean, 50–79 fair, 20–49 poor, below 20 high risk.

Datacenter IPs belong to cloud and hosting companies such as AWS, Google Cloud or OVH, and many websites treat them as likely proxies. Residential IPs are assigned to home users by consumer ISPs such as Comcast, BT or Deutsche Telekom, so websites trust them more.

Either you are using a proxy or VPN right now, or the address appears on public proxy lists or in a VPN provider's ranges. An address your ISP has reassigned can also carry an old flag for a while.

Many platforms compare your browser's time zone and language with where your IP is. A mismatch doesn't mean the IP is bad, but it makes your setup look less consistent. Setting them to match the IP's location helps.

Good enough to use as a guide, but every platform has its own risk rules, so the score isn't any platform's final decision.
