Questions about AS38638
Is AS38638 a VPN or hosting network?
Fraudex does not list AS38638 (IP-CORE) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS38638 registered in?
AS38638 is registered in Japan. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS38638 have?
It announces 10 IPv4 ranges with 6,400 addresses in total.
How do I block traffic from AS38638?
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.
