Questions about AS721

Is AS721 a VPN or hosting network?

Fraudex does not list AS721 (DNIC-ASBLK-00721-00726) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.

Which country is AS721 registered in?

AS721 is registered in United States. Individual addresses can be used elsewhere, so check the IP itself when location matters.

How many IP addresses does AS721 have?

It announces 2,256 IPv4 ranges with 29,226,752 addresses in total, plus 8 IPv6 ranges.

How do I block traffic from AS721?

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.
