Questions about AS59253
Is AS59253 a VPN or hosting network?
Yes. Fraudex lists AS59253 (LEASEWEB-APAC-SIN-11) among the hosting, VPN, proxy and bot networks it flags, so visitors from it are usually servers or people hiding their real location rather than ordinary customers.
Which country is AS59253 registered in?
AS59253 is registered in Singapore. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS59253 have?
It announces 65 IPv4 ranges with 45,822 addresses in total, plus 4 IPv6 ranges.
How do I block traffic from AS59253?
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.
