Questions about AS331

Is AS331 a VPN or hosting network?

Fraudex does not list AS331 (DNIC-ASBLK-00306-00371) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS331 registered in?

AS331 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS331 have?

It announces 6 IPv4 ranges with 196,608 addresses in total.

How do I block traffic from AS331?

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.
