Questions about AS21559

Is AS21559 a VPN or hosting network?

Fraudex does not list AS21559 (OSNET) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS21559 registered in?

AS21559 is registered in Puerto Rico. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS21559 have?

It announces 34 IPv4 ranges with 31,488 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS21559?

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.
