Interface configuration - Internet not working

Question

I just tried to configure eth0 interface on my Ubuntu Server 14.04 Lts.

I want to set up static ip, therefore I put the following lines in /etc/network/interfaces:

## To configure a dynamic IP address
auto eth0
iface eth0 inet dhcp

## Or configure a static IP
auto eth0
iface eth0 inet static
  address 192.168.1.111
  gateway 192.168.1.1
  netmask 255.255.255.0
  network 192.168.1.0
  broadcast 192.168.1.255

I can perfectly ping my router with this configuration. I also can connect to the server from my laptop via ssh. But internet is not working:

ping google.de
ping: unknown host google.de

What could be wrong here?

No, just leave it. It'll be closed as a duplicate and might serve others bumping into your question with the same issue. — David Foerster, Oct 18 '15 at 08:56

You have not specified a nameserver for the static configuration.

Append a stanza

 dns-nameservers 192.168.1.1

or whatever DNS you like to use. Specify multiple DNS server as a space-separated list.

Bring the interface down and up to trigger resolvconf

 sudo ifdown eth0 && sudo ifup eth0
