I have noticed this as well. And not just IE. It seems it's not uncommon for an app to use the local host API's to get an address, and then continue using that address for the life of its own process (or at least for some extended period).
Close and re-spawn the process, and the subsequent OS API call to get the IP address results in getting the "correct" new one. -sc > -----Original Message----- > From: David Lum [mailto:[email protected]] > Sent: Thursday, June 14, 2012 2:45 PM > To: NT System Admin Issues > Subject: RE: Windows XP DNS Cache Retention time question > > " Also it seems IE has its own cache.
