Review Comment:
> well... another concern is that test is not actually testing the new code.
How can you guarantee the codebase of NetworkUtil itself?
Well kinda testing the logics of the new code. I've difficulty in testing
the new code itself mainly because I couldn't find a good way to simulate
InetAddress methods. So I do a wrapper just to mock those methods but the logic
is real.

> The method just compares the host names using string equals. However when one
> host name is in IP form (like "10.7.2.2") it should try to resolve the
> addresses of the host name and make sure they are equal if one of the IP
> addresses matches. Otherwise it may return wrong comparison result.
> Also when comparing localhost it should take care of the case where the host
> is absent from the transport configuration.
