is there any major benefit of using alternate dns?

They log IP or MAC address...reason is almost all VPN restrict number of concurrent connections that can be used

 

[JB701]

They don't need to log IP or MAC to restrict connections. They can simply see how many users are connected at a time.

VPN service provider logs your ip when you connect to their service. Without knowing your ip it cannot send or receive packets. It will be cleared when server restarts.

This is when multiple hops vpn become useful as the last vpn server will log ip of first vpn server. I think with mullvad you can have 3 hops, last one as browser proxy.

yes true, but here I meant store "long term"
