Questions about AS38731

Is AS38731 a VPN or hosting network?

Fraudex does not list AS38731 (VTDC-AS-VN) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS38731 registered in?

AS38731 is registered in Vietnam. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS38731 have?

It announces 31 IPv4 ranges with 64,512 addresses in total, plus 2 IPv6 ranges.

How do I block traffic from AS38731?

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.
