Questions about AS18403
Is AS18403 a VPN or hosting network?
Fraudex does not list AS18403 (FPT-AS-AP) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS18403 registered in?
AS18403 is registered in Vietnam. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS18403 have?
It announces 312 IPv4 ranges with 1,423,096 addresses in total, plus 478 IPv6 ranges.
How do I block traffic from AS18403?
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.
