Questions about AS11537

Is AS11537 a VPN or hosting network?

Fraudex does not list AS11537 (INTERNET2-RESEARCH-EDU) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS11537 registered in?

AS11537 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS11537 have?

It announces 18 IPv4 ranges with 7,480 addresses in total, plus 28 IPv6 ranges.

How do I block traffic from AS11537?

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.
