Questions about AS81

Is AS81 a VPN or hosting network?

Fraudex does not list AS81 (NCREN) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS81 registered in?

AS81 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS81 have?

It announces 68 IPv4 ranges with 2,055,424 addresses in total, plus 8 IPv6 ranges.

How do I block traffic from AS81?

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.
