i can't remove file above, the story behind it:
dns servers are usually provided by isp
but they can't be used with vpn
so vpn provider told me to make a special resolv.conf
which contains dns servers not provided isp
dns server by vpn provider is useful when i visit blocked sites
but they are not as fast as those by isp
my question is  how to change dns server as needed?
it seem that resolv.conf is automatically managed
and how to remove the special resolv.conf

What application do you use to manage your network connections? I use NetworkManager, which manages resolve.conf. I find this more convenient than manually editing resolv.conf. My resolv.conf starts with:

# Generated by NetworkManager

If I use the NetworkManager desktop applet to access the connection editor (nm-connection-editor), I can edit the connection; under IPv4 Settings, I set Method Manual and list the DNS servers for this connection. I can also see the DNS servers listed under the Connection Information. The default behaviour is to use the DNS server supplied via DHCP, for example, from your router (likely the router itself). You will likely need two connections: one for your main connection and one for your VPN. I suggest adding custom DNS servers under your VPN connection settings.

Kind regards,
