Windows 7 / IPv6 on PPP Adapter

2013-07-17 Thread Liviu Pislaru
What is your opinion about Windows 7 IPv6 over PPP behaviour that i'm going to describe below ? if the global IPv6 address of the PPP interface has the last 64 bits different from the last 64 bits of the IPv6 Link Local address (interface identifier negociated by IPv6CP), then IPv6 is not

Ron, I am too. I would really like to see 6to4 and teredo be default off everywhere, and people who want it can manually turn it on. If teredo went away completely, that would also be a good thing. Strongly concur here as well. One less thing I have to disable on all my systems in

Hi, off the top of my head it's roughly as follows: a) 6to4 Win7/Server 2008 generation and before: if IPv4 address = Non-RFC 1918 address, automatically enable 6to4 and try to resolve 6to4.ipv6.microsoft.com to get 'nearest relay'. no idea as for Win8/Server 2012. b) Teredo Vista: enable

Hi, thanks for that link. big questions is: what means disabling IPv6 in those contexts? unchecking IPv6 in GUI based interface properties? setting DisabledComponents to 0xfff? using some netsh-based approach? from what I hear: as long as you can successfully ping ::1, IPv6 is considered
