Questions about AS2852

Is AS2852 a VPN or hosting network?

Fraudex does not list AS2852 (CESNET2) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS2852 registered in?

AS2852 is registered in Czechia. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS2852 have?

It announces 20 IPv4 ranges with 849,920 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS2852?

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.
