Questions about AS25048
Is AS25048 a VPN or hosting network?
Yes. Fraudex lists AS25048 (DSNET) 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 AS25048 registered in?
AS25048 is registered in United Kingdom. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS25048 have?
It announces 3 IPv4 ranges with 3,328 addresses in total, plus 3 IPv6 ranges.
How do I block traffic from AS25048?
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.
