 Normally we just add the IP Address, Subnet Mask and Gateway to the ifcfg-eth0 file, as that is all we need. But if it is required that we need to update the OS, or add a piece of software (htop for example) then we may need to add the DNS settings.

 ==== Method 2 ====

+Alternatively, you can specify DNS servers directly in the interface configuration file, instead of modifying /etc/resolv.conf yourself. That is:
+\\
+\\
+**//sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0//**
+\\
+\\
+DEVICE=eth0\\
+BOOTPROTO=dhcp\\
+ONBOOT=yes\\
+**DNS1=8.8.8.8**\\
+**DNS2=8.8.4.4**\\
+\\
+\\
+The DNS servers specified with "DNS1/DNS2" directives will then automatically be added to **/etc/resolv.conf** when the interface is activated. So there is no need to modify **/etc/resolv.conf** yourself.
