Questions about AS72

Is AS72 a VPN or hosting network?

Fraudex does not list AS72 (SCHLUMBERGER-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS72 registered in?

AS72 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS72 have?

It announces 68 IPv4 ranges with 1,152,256 addresses in total.

How do I block traffic from AS72?

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.
