Questions about AS19133
Is AS19133 a VPN or hosting network?
Yes. Fraudex lists AS19133 (BIRD-HOSTING) 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 AS19133 registered in?
AS19133 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS19133 have?
It announces 11 IPv4 ranges with 13,824 addresses in total, plus 5 IPv6 ranges.
How do I block traffic from AS19133?
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.
