Questions about AS17638
Is AS17638 a VPN or hosting network?
Fraudex does not list AS17638 (CHINATELECOM-TJ-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 AS17638 registered in?
AS17638 is registered in China. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS17638 have?
It announces 141 IPv4 ranges with 602,624 addresses in total, plus 16 IPv6 ranges.
How do I block traffic from AS17638?
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.
