I set static DNS in /etc/resolvconf/resolv.conf.d/base file:


But my PC still obtains DNS from DHCP, this is my /etc/resolv.conf:


How to ignore obtained DNS from DHCP server?


You can add this line to your /etc/dhcp/dhclient.conf:

supersede domain-name-servers,;

Then restart network or run dhclient to make changes.

From man dhclient.conf:

The supersede statement

       supersede [ option declaration ];

       If for some option the client should always  use  a  locally-configured
       value  or  values rather than whatever is supplied by the server, these
       values can be defined in the supersede statement.

    Also you can comment out in /etc/dhcp/dhclient.conf in request parameters that you don't want to request, for DNS it can be domain-name, domain-name-servers, domain-search. – Alex Nov 8 '16 at 10:20
