Questions about AS51191
Is AS51191 a VPN or hosting network?
Yes. Fraudex lists AS51191 (XIRRA) 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 AS51191 registered in?
AS51191 is registered in Germany. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS51191 have?
It announces 7 IPv4 ranges with 7,168 addresses in total, plus 7 IPv6 ranges.
How do I block traffic from AS51191?
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.
