What does “sudo echo nameserver 8.8.8.8 > /etc/resolv.conf” do?

0 votes
My internet connection has been really slow and I was getting a few errors saying network unreachable and stuff. I googles it and somewhere it said to add nameserver 8.8.8.8 in my etc/resolve.conf file.

I tried that solution and my internet started working like a charm. Now I'm just very curious about what changes did this command make to my network.

If executing this command resolved your issue then you were probably facing DNS network issue. This command basically replaces your nameserver or DNS used on your machine by Google's public DNS.
