Which country is AS53559 registered in?
AS53559 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS53559 have?

How do I block traffic from AS53559?
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.
