--dns args

When should you use "--dns”? How does it function differently than “dhcp-option”? Is its implementation vpn provider-specific?

When you use
--dns server n transport DoT
does it magically encrypt any DNS queries routed over the tunnel, or what actually happens?

I use “--dhcp-option” all the time
I’ve never used "--dns option"

could you point us to a useful resource to help understand? Thank you!

I think the majority of the options would only be relevant in a private VPN setup, e.g. LAN to LAN. When connecting to a commercial VPN provider like NordVPN the only --dhcp-option that seems useful is DNS (and perhaps DOMAIN). The new --dns options seem more aimed at setting environment variables that can be used in scripts.

What options do you use?
