Questions about AS18881

Is AS18881 a VPN or hosting network?

Fraudex does not list AS18881 (TELEFONICA) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS18881 registered in?

AS18881 is registered in Brazil. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS18881 have?

It announces 162 IPv4 ranges with 4,581,376 addresses in total, plus 27 IPv6 ranges.

How do I block traffic from AS18881?

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.
