Prevent DNS leaks

0. go online and find a trustworthy dns service
locate the IP address

1. edit the /etc/resolv.conf
comment out any nameserver
then add your nameserver with the IP address you found

2. it should look like the example resolv.conf.txt

3. do not restart NetworkManager because it will preload the file and will use the DNS server from your ISP

example resolv.conf

# not sure what this does
domain tx.rr.com

# the original DNS IP addresses
#nameserver 209.18.47.61
#nameserver 209.18.47.62

# new ones
# we have 2 just in case one fails
nameserver
