Unable to resolve hos

[dvdobrovolskiy]

Found it generate exception then there is no internet. Exception fired then accessing CloudBlobContainer like

container.exists()

or

CloudBlockBlob blob1 = container
.getBlockBlobReference("Name.ext");

Exception is -
Unable to resolve host "SOMENAME.blob.core.windows.net": No address associated with hostname

Do I need to check internet connection my self (in this case I am afraid I still cannot do it in most proper way) or this library has build in mechanism to check this?
