Questions about AS18305
Is AS18305 a VPN or hosting network?
Fraudex does not list AS18305 (POSNET) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS18305 registered in?
AS18305 is registered in South Korea. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS18305 have?
It announces 35 IPv4 ranges with 75,264 addresses in total.
How do I block traffic from AS18305?
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.
