Questions about AS24253

Is AS24253 a VPN or hosting network?

Fraudex does not list AS24253 (J-STREAM) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS24253 registered in?

AS24253 is registered in Japan. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS24253 have?

It announces 2 IPv4 ranges with 2,304 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS24253?

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.
