Questions about AS18558

Is AS18558 a VPN or hosting network?

Fraudex does not list AS18558 (NETBLK-RCOEK) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS18558 registered in?

AS18558 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS18558 have?

It announces 32 IPv4 ranges with 72,204 addresses in total, plus 5 IPv6 ranges.

How do I block traffic from AS18558?

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.
