Windows 7 handling RA and RDNSS

My last blog posted touched on IPv6 RA with RDNSS and I like to thank my reader Revellion for reminding me that Windows 7 machines do not support RDNSS in RA.


Actually, I had some experience on a different scenario. During APRICOT-APAN 2011, I used a IPv6 only network and the v6 address assigned to my Window 7 machine was quite like auto-configuration but there was the assignment of v6 DNS resolvers. I was mindful that Windows 7 could not support RA with RDNSS and the question was where come the assignment of v6 DNS resolvers. The answer was that the network was using a DHCPv6 to assign DNS resolvers while there was a RADVD to accomplish the task of auto-config IPv6 address for clients. Up to this point, I should fire a bullet at Microsoft for not releasing patches to make RA working with RDNSS. This would save the unnecessary provision of a DHCPv6 server.


Luckily, I still keep a picture of the configuration for reference which is posted  below.
