Questions about AS57043
Is AS57043 a VPN or hosting network?
Yes. Fraudex lists AS57043 (HOSTKEY-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 AS57043 registered in?
AS57043 is registered in Netherlands. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS57043 have?
It announces 354 IPv4 ranges with 125,952 addresses in total, plus 9 IPv6 ranges.
How do I block traffic from AS57043?
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.
