Encontrar los DNS de Ubuntu

En Windows si quieres ver qué DNS está usando tu ordenador puedes ir al terminal y escribir ipconfig /all. ¿Cómo hacerlo en Ubuntu?

Fácil, es curioso como también es por terminal (hay cosas que se hacen más fácil así). Abrimos un terminal y dos opciones:

1. nslookup dominio Donde dominio es, por ejemplo google.es , te dará uno o dos “servers” y su dirección como primera respuesta (además de las ips de Google). Esos son tus dns.
2. cat /etc/resolv.conf  También te dice los DNS  (nameserver) que estás usando. Y puedes cambiarlos con

   sudo gedit /etc/resolv.conf

Si lo que obtienes es 127.0.1.1 (Debian, Ubuntu) , 127.0.0.1 0 192.168.1.1  lo más seguro es que estés por DHCP y los DNS los esté gestionando tu router. Puedes poner alguno (como los de  Google o OpenDNS) a mano o con la interfaz de conexiones de red.
