+==== DNS-/ DHCP ====
+If you want to **override** the DNS servers **provided by DHCP entirely** and force the system to use the ones you provide, use the **supersede** entry:
+  /etc/dhcp/dhclient.conf
+  supersede domain-name-servers 127.0.0.1;
+  supersede domain-name-servers 12.34.56.78, 12.34.56.79;
+<code>
+cat /etc/resolv.conf
+nameserver 127.0.0.1
+</code>
+"**prepend**" add servers to those provided by dhcp (work as a fallback):
+  prepend domain-name-servers 12.34.56.78, 12.34.56.79;
