Questions about AS1104
Is AS1104 a VPN or hosting network?
Fraudex does not list AS1104 (NIKHEF) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS1104 registered in?
AS1104 is registered in Netherlands. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS1104 have?
It announces 9 IPv4 ranges with 75,264 addresses in total, plus 4 IPv6 ranges.
How do I block traffic from AS1104?
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.
