Questions about AS39351
Is AS39351 a VPN or hosting network?
Yes. Fraudex lists AS39351 (ESAB-AS) among the hosting, VPN, proxy and bot networks it flags, so visitors from it are usually servers or people hiding their real location rather than ordinary customers.
Which country is AS39351 registered in?
AS39351 is registered in Sweden. Individual addresses can be used elsewhere, so check the IP itself when location matters.
How many IP addresses does AS39351 have?
It announces 31 IPv4 ranges with 14,336 addresses in total, plus 11 IPv6 ranges.
How do I block traffic from AS39351?
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.
