Questions about AS41733
Is AS41733 a VPN or hosting network?
Fraudex does not list AS41733 (ZTELECOM-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS41733 registered in?
AS41733 is registered in Russia. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS41733 have?
It announces 36 IPv4 ranges with 292,608 addresses in total.
How do I block traffic from AS41733?
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.
