Questions about AS1840

Is AS1840 a VPN or hosting network?

Which country is AS1840 registered in?

How many IP addresses does AS1840 have?

How do I block traffic from AS1840?

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.
