Not flagged: treated as regular traffic

AS2907 is not on Fraudex's VPN, proxy and datacenter list, so its IPs are treated like ordinary home, mobile or business connections. A single address can still be flagged if it is a Tor exit relay.

Questions about AS2907

Is AS2907 a VPN or hosting network?

Fraudex does not list AS2907 (SINET-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS2907 registered in?

AS2907 is registered in Japan. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS2907 have?

It announces 410 IPv4 ranges with 8,769,344 addresses in total, plus 2 IPv6 ranges.

How do I block traffic from AS2907?

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.
