I want to route all my traffic through a VPN (Ipredator). I plan to use ufw under Ubuntu.
I have e-mailed Ipredator but they have not responded as yet and I understand that their customer service is not the best.
My impression is that IPREDator are served by ViaEuropa Routingregistry (viaeuropa.net). Their CIDR is 184.108.40.206/18
However, there are IPs in this range which do not resolve to Ipredator.
220.127.116.11.in-addr.arpa domain name pointer anon-137-1.relakks.com
Is there a professional way of removing such IPs or would it just be easier to just use 18.104.22.168-22.214.171.124 (based on 126.96.36.199/18) as the only IP addresses to which I am permitted to connect?
I guess another way to ask this question is: what are the tools you would use to define the specific IP addresses to target?
