Questions about AS203997

Is AS203997 a VPN or hosting network?

Fraudex does not list AS203997 (XTDEF) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS203997 registered in?

AS203997 is registered in Hong Kong. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS203997 have?

It announces 6 IPv4 ranges with 1,536 addresses in total, plus 2 IPv6 ranges.

How do I block traffic from AS203997?

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.
