Do you know that most recent versions of OSes whether Microsoft, Apple, Linux or Solaris are shipped with IPV6 enabled by default? And this has both security and network speed implications?
“Do you know whether your computers are actively using IPv6 or not? Better check, as the bad guys probably already know.
Microsoft began enabling IPv6 protocol by default with the release of Vista.
That policy continued with Windows Server 2008 and will with Windows 7. Apple, Linux, and Solaris are also shipping their latest distributions with IPv6 enabled.”
Computers with their IPV6 turned “ON” are estimated to be around 300 million computers and most users probably are not aware of it.
An article by Michael Kassner in ZDNet Asia “IPv6: Oops, it’s on by default” [url: http://www.zdnetasia.com/techguide/security/0,39044901,62056959,00.htm?scid=nl_z_tgis] discusses the implications (security and network speed) and several reasons or situations why you need IPV6 turned “OFF” or “ON”, what you need to do if you need it turned “ON” and provides links on references on how to turn them “OFF” for several OS: Microsft, Apple and Linux.
