Questions about AS1653

Is AS1653 a VPN or hosting network?

Fraudex does not list AS1653 (SUNET) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS1653 registered in?

AS1653 is registered in European Union. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS1653 have?

It announces 70 IPv4 ranges with 488,959 addresses in total, plus 2 IPv6 ranges.

How do I block traffic from AS1653?

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.
