Questions about AS7539

Is AS7539 a VPN or hosting network?

Fraudex does not list AS7539 (TWAREN-TW) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS7539 registered in?

AS7539 is registered in Taiwan. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS7539 have?

It announces 9 IPv4 ranges with 85,504 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS7539?

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.
