Questions about AS3303

Is AS3303 a VPN or hosting network?

Fraudex does not list AS3303 (SWISSCOM) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS3303 registered in?

AS3303 is registered in Switzerland. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS3303 have?

It announces 252 IPv4 ranges with 3,497,728 addresses in total, plus 37 IPv6 ranges.

How do I block traffic from AS3303?

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.
