--- Comment #11 from Juan Lang juan_lang@yahoo.com 2008-05-20 17:13:40 --- That's the case in Windows too, I just checked. I also checked the '<Default>' entry in Windows: it also has an empty IP address. So the only bug left is that adapters have a name of '<Unknown>' in Wine, for which I've sent a patch.
Please don't waste our time with bogus complaints. A behavior is only a bug if it behaves differently in Wine than in Windows.
