У меня есть выделенный сервер с CentOS 6, WHM. Сервер отвечает очень медленно. Использование ресурсов менее 10%. Пытаясь устранить неполадки, я обнаружил, что не могу использовать команду ping

вот что я получаю

root@power [/tmp]# curl -v google.com
* getaddrinfo(3) failed for google.com:80
* Couldn't resolve host 'google.com'
* Closing connection #0
curl: (6) Couldn't resolve host 'google.com'

=========== Вот верхний результат

Любая помощь? Заранее извините за плохой английский
