IPFastCheck
A 0–100 risk score with flags for proxy, VPN, Tor, datacenter, fraud, abuse and blacklists.
- Score 0–100
What it is
IPFastCheck is a free IP reputation lookup. It combines proxy and VPN detection data, the official Tor exit list, datacenter ranges taken from autonomous-system data and blacklist hits into one score.
It also tells home addresses from datacenter ones, which matters when you judge whether traffic looks human.
What it checks
- Commercial proxy and VPN detection databases
- The official Tor exit node list
- Datacenter and hosting ranges
- Blacklist hits and historical abuse signals
How to read the result
- 0–34
- Clean.
- 35–69
- Caution: some signals, worth a closer look.
- 70–100
- High risk. A single strong flag (proxy, VPN, Tor, fraud, blacklist) is enough for this verdict on the service’s own page.
Colours on this site: green below 30, yellow 30–59, red from 60.
Limits
- The service is young and its detection data is not published.
- A datacenter flag is not abuse by itself — many legitimate servers live there.
