ipv6 privacy extensions
Windows 8.1
I'm finally trying to get me head around ipv6 I was somewhat alarmed to discover that the low order 64 bits are reserved for what someone called 'hardware addressing schemes' but I can't remember where I read this. https://en.wikipedia.org/wiki/IPv6 "In IPv6 when using address auto-configuration, the Interface Identifier (MAC address) of an interface port is used to make its public IP address unique, exposing the type of hardware used and providing a unique handle for a user's online activity" The article then goes on about 'privacy extensions' "Privacy extensions are enabled by default in Windows (since XP SP1), OS X (since 10.7), and iOS (since version 4.3). Some Linux distributions have enabled privacy extensions as well" If I open a command window I get Physical Address. . . . . . . . . : 6C-FA-A7-3A-45-AC .... DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-1C-E1-07-B6-6C-FA-A7-3A-45-AC and can see the physical address on the end of the DUID. The local library recently demanded the wireless interface MAC addresses from our local user groups laptops saying it would 'make our lives easier as we no longer had to log in to the wireless network' but I suspect it has more to do with tracking our usage. Am I right to be concerned? Thanks -- Quis custodiet ipsos custodes? Who watches the watchers? (loose translation) |

Am I right to be concerned? Let me get this straight, you want to know if a government entity (a library) might be tracking and logging your use of their Internet connection? |
