Questions about AS20559

Is AS20559 a VPN or hosting network?

Fraudex does not list AS20559 (FUNDAMENTS-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS20559 registered in?

AS20559 is registered in Netherlands. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS20559 have?

It announces 28 IPv4 ranges with 33,280 addresses in total, plus 7 IPv6 ranges.

How do I block traffic from AS20559?

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.
