Questions about AS45903
Is AS45903 a VPN or hosting network?
Fraudex does not list AS45903 (CMCTELECOM-VN) as a VPN, proxy or hosting network. Its addresses are treated as regular traffic, apart from any Tor exit relays.
Which country is AS45903 registered in?
AS45903 is registered in Vietnam. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS45903 have?
It announces 31 IPv4 ranges with 80,380 addresses in total, plus 31 IPv6 ranges.
How do I block traffic from AS45903?
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.
