Questions about AS37963

Is AS37963 a VPN or hosting network?

Fraudex does not list AS37963 (ALIBABA-CN-NET) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS37963 registered in?

AS37963 is registered in China. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS37963 have?

It announces 127 IPv4 ranges with 9,303,296 addresses in total, plus 25 IPv6 ranges.

How do I block traffic from AS37963?

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.
