Questions about AS3372

Is AS3372 a VPN or hosting network?

Fraudex does not list AS3372 (MCI-ASN) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS3372 registered in?

AS3372 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS3372 have?

It announces 52 IPv4 ranges with 424,704 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS3372?

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.
