Questions about AS138421

Is AS138421 a VPN or hosting network?

Fraudex does not list AS138421 (CU-CN-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS138421 registered in?

AS138421 is registered in China. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS138421 have?

It announces 87 IPv4 ranges with 71,168 addresses in total, plus 20 IPv6 ranges.

How do I block traffic from AS138421?

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.
