Questions about AS28391

Is AS28391 a VPN or hosting network?

Fraudex does not list AS28391 (Universidad Juarez Autonoma de Tabasco) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS28391 registered in?

AS28391 is registered in Mexico. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS28391 have?

It announces 33 IPv4 ranges with 41,216 addresses in total.

How do I block traffic from AS28391?

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.
