====== Redhat - Networking - dhclient.conf ======

===== Change dhclient.conf =====

Edit /etc/dhcp3/dhclient.conf

<WRAP important>
**NOTE:**  You may need to modify /etc/dhcp/dhclient.conf instead of /etc/dhcp3/dhclient.conf
</WRAP>


Then find the following line

<file bash /etc/dhcp3/dhclient.conf>
#prepend domain-name-servers 127.0.0.1;
</file>

And change it to

<file bash /etc/dhcp3/dhclient.conf>
prepend domain-name-servers 8.8.8.8;
</file>

This will make dhclient (the DHCP client that NetworkManager uses) prepend this to your dns servers, so resolve.conf will end up looking like this

<file bash /etc/dhcp3/dhclient.conf>
nameserver 8.8.8.8
nameserver 192.168.1.1
</file>

This solution will work everywhere and you will always get the DNS that you have chosen as the primary one.
