Questions about AS38387
Is AS38387 a VPN or hosting network?

Which country is AS38387 registered in?
AS38387 is registered in South Korea. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS38387 have?
It announces 6 IPv4 ranges with 5,632 addresses in total.
How do I block traffic from AS38387?
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.
