Questions about AS17857

Is AS17857 a VPN or hosting network?

Fraudex does not list AS17857 (SKB-NAKDONGDIGITALBUSANNET-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 AS17857 registered in?

AS17857 is registered in South Korea. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS17857 have?

It announces 63 IPv4 ranges with 145,408 addresses in total.

How do I block traffic from AS17857?

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.
