Questions about AS51290
Is AS51290 a VPN or hosting network?
Yes. Fraudex lists AS51290 (HOSTEAM-AS) 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 AS51290 registered in?
AS51290 is registered in Poland. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS51290 have?
It announces 6 IPv4 ranges with 5,888 addresses in total, plus 2 IPv6 ranges.
How do I block traffic from AS51290?
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.
