Questions about AS31477

Is AS31477 a VPN or hosting network?

Fraudex does not list AS31477 (DUOCAST-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS31477 registered in?

AS31477 is registered in Netherlands. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS31477 have?

It announces 31 IPv4 ranges with 30,976 addresses in total, plus 12 IPv6 ranges.

How do I block traffic from AS31477?

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.
