Questions about AS3257

Is AS3257 a VPN or hosting network?

Fraudex does not list AS3257 (GTT-BACKBONE) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS3257 registered in?

AS3257 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS3257 have?

It announces 2,134 IPv4 ranges with 4,648,192 addresses in total, plus 69 IPv6 ranges.

How do I block traffic from AS3257?

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.
