Questions about AS1149

Is AS1149 a VPN or hosting network?

Fraudex does not list AS1149 (SURFNET-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS1149 registered in?

How many IP addresses does AS1149 have?

It announces 2 IPv4 ranges with 1,024 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS1149?

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.
