Questions about AS17841

Is AS17841 a VPN or hosting network?

Fraudex does not list AS17841 (NCIA-AS-KR) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS17841 registered in?

AS17841 is registered in South Korea. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS17841 have?

It announces 104 IPv4 ranges with 224,768 addresses in total.

How do I block traffic from AS17841?

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.
