I'm securing our networks and want to be able to whitelist all known Torguard VPN ip addresses for accessing my network. I read that I have to use the dig command, but I only get one result when I do. I am able to get all the Torguard servers via here: https://torguard.net/network/
I am not sure what I'm doing wrong to fetch the IP's of each region. I want to know all the different IP ranges of that region.
