I've looked for a while in the internet, and searched on how can i find out which Domain Name System server my machine is using.
All the links said that i have to look in the file
/etc/resolv.conf, but when i open this file, the only address I see is
What is happening here ?! How can my machine be the DNS server i'm using ?
PS : I'm using ubuntu 15.10 (with Linux version > 4)
