the reasons to switch to other DNS servers for performance, privacy and censorship. Most of the people using OpenDNS as the first alternative, But Now Google Public DNS is available and the performance is much better.

Put these nameserver addresses as your ‘DNS Servers’:8.8.8.8, 8.8.4.4

Thanks to FOSS

but i think i should backup my DNS server addresses first i run the following command to do it :


sudo cat /etc/resolv.conf >> /home/zero/Desktop/DNS_Backup

Change zero to your username.

the above command will save a file in your desktop that conatin the address of your DNS server, it's output should look like this:


# Generated by NetworkManager
nameserver 196.29.180.19
nameserver 196.29.164.29
