Slow dns fix!

[ghost_ryder35]

If you are experiencing slow DNS in Fedora, here is a great workaround instead of disabling IPV6. Just add options single-request to /etc/resolv.conf if you are running 'network'
Edit this file

vi /etc/resolv.conf

Add options single-request to bottom of file and save

nameserver 4.2.2.1
nameserver 4.2.2.3
options rotate
options single-request

If you are running 'NetworkManager' and know how to add options to /etc/resolv.conf when it gets built post the steps below and I will add them here.

Thanks for the post!

To add this to my /etc/resolv.conf file when using NetworkManager, I created a script in /etc/NetworkManager/dispatcher.d called 06-dhclientoptions

#!/bin/bash
#
# This is for adding any custom dhclient options to the end of /etc/resolve.conf file
#
# 2010.09.15 - Created
#
echo "options single-request" >> /etc/resolv.conf

Also, remember to chmod +x /etc/NetworkManager/dispatcher.d/06-dhclientoptions
