Questions about AS44066

Is AS44066 a VPN or hosting network?

Yes. Fraudex lists AS44066 (DE-FIRSTCOLO) among the hosting, VPN, proxy and bot networks it flags, so visitors from it are usually servers or people hiding their real location rather than ordinary customers.

Which country is AS44066 registered in?

AS44066 is registered in Germany. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS44066 have?

It announces 84 IPv4 ranges with 147,968 addresses in total, plus 17 IPv6 ranges.

How do I block traffic from AS44066?

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.
