Questions about AS21453
Is AS21453 a VPN or hosting network?
Fraudex does not list AS21453 (FLEX-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS21453 registered in?
AS21453 is registered in Russia. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS21453 have?
It announces 15 IPv4 ranges with 117,248 addresses in total, plus 1 IPv6 range.
How do I block traffic from AS21453?
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.
