ip reputation

Wikipedia blocks single IPs, whole ranges, and accounts. Why you are blocked when you never edited, how to read the block notice, and the legitimate ways to edit again.

Cloudflare error 1020 means a rule the site owner configured blocked your request. What triggers it, how to tell whether your IP or your request set it off, and how to fix it.

Check whether an IP is blacklisted the way the blocklists work: a reversed-IP DNSBL lookup, reading the 127.0.0.x return codes, and the traps that fake a result.

A site says VPN or proxy detected when your exit is on a known-proxy list or a hosting range, or leaks a proxy header. Why it happens, what gives you away, and how to read as a real connection.

A clean IP is an address no site has flagged yet: off every blocklist, no abuse history, owned by a real ISP, and low fraud score. What that means and how to check yours.

An IP fraud score rates how risky your address looks, usually 0 to 100 where lower is better. What sets it, what counts as good, and how a clean proxy reads near zero.

Why your IP is blocked: the address reads as a data center, it is on a blocklist, or it made too many requests. How to tell which, and how to get a clean exit.
