Questions about AS16973

Is AS16973 a VPN or hosting network?

Yes. Fraudex lists AS16973 (T-Four) 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 AS16973 registered in?

AS16973 is registered in Costa Rica. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS16973 have?

It announces 2 IPv4 ranges with 3,072 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS16973?

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.
