Is AS51241 a VPN or hosting network?

Which country is AS51241 registered in?
AS51241 is registered in Iran. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS51241 have?
It announces 3 IPv4 ranges with 1,536 addresses in total.
How do I block traffic from AS51241?
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.
