Questions about AS1540

Is AS1540 a VPN or hosting network?

Fraudex does not list AS1540 (DNIC-ASBLK-01534-01546) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS1540 registered in?

AS1540 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS1540 have?

It announces 249 IPv4 ranges with 3,224,064 addresses in total, plus 17 IPv6 ranges.

How do I block traffic from AS1540?

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.
