No se puede resolver un solo sitio desde el interior del huésped virtual en caja Ubuntu 14.04 (64 bits)

Question

Curiosamente, puedo acceder desde el sistema operativo invitado a todos los sitios, perobitbucket.org, mientras que puede acceder a él desde el sistema operativo host.

¿Alguna idea, por qué?

Si no puede resolver bitbucket.org, lo más probable es que la culpa sea de su servidor DNS. Para verificar lo mismo, simplemente consulte desde otro servidor DNS como este:

nslookup bitbucket.org 8.8.8.8
