From the Tor Project's current exit list. Fraudex flags these addresses even though the network itself is already flagged.
Questions about AS51167
Is AS51167 a VPN or hosting network?
Yes. Fraudex lists AS51167 (CONTABO) among the hosting, VPN, proxy and bot networks it flags, so visitors from it are usually servers or people hiding their real location rather than ordinary customers.
Which country is AS51167 registered in?
AS51167 is registered in Germany. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS51167 have?
It announces 219 IPv4 ranges with 460,800 addresses in total, plus 3 IPv6 ranges.
How do I block traffic from AS51167?
Blocking a whole network by number goes stale as ranges change hands. It is more reliable to check each visitor's IP when they sign up, log in or pay: the Fraudex API returns the network and a VPN and bot verdict, so you can block, challenge or just log flagged traffic. See why an IP blocking API pays for itself.
