Questions about AS25577

Is AS25577 a VPN or hosting network?

Fraudex does not list AS25577 (C4L-AS) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS25577 registered in?

AS25577 is registered in United Kingdom. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS25577 have?

It announces 43 IPv4 ranges with 49,664 addresses in total, plus 1 IPv6 range.

How do I block traffic from AS25577?

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.
