Description

I just hit this failure. We should use some more unique string for "UnknownHost":

Testcase: testNormalizeHostName took 0.007 sec
FAILED
expected:<[65.53.5.181]> but was:<[UnknownHost]>
junit.framework.AssertionFailedError: expected:<[65.53.5.181]> but was:<[UnknownHost]>

Will post a patch in a bit.
