Questions about AS7738

Is AS7738 a VPN or hosting network?

Fraudex does not list AS7738 (V) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS7738 registered in?

AS7738 is registered in Brazil. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS7738 have?

It announces 99 IPv4 ranges with 1,661,952 addresses in total, plus 2 IPv6 ranges.

How do I block traffic from AS7738?

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.
