Which country is AS197731 registered in?

How many IP addresses does AS197731 have?
It announces 8 IPv4 ranges with 6,912 addresses in total, plus 3 IPv6 ranges.
How do I block traffic from AS197731?
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.
