Questions about AS1831

Is AS1831 a VPN or hosting network?

Fraudex does not list AS1831 (ITESO,) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS1831 registered in?

AS1831 is registered in Mexico. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS1831 have?

It announces 2 IPv4 ranges with 65,536 addresses in total.

How do I block traffic from AS1831?

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.
