Questions about AS21430

Is AS21430 a VPN or hosting network?

Fraudex does not list AS21430 (WIA-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS21430 registered in?

AS21430 is registered in Czechia. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS21430 have?

It announces 51 IPv4 ranges with 41,472 addresses in total, plus 4 IPv6 ranges.

How do I block traffic from AS21430?

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.
