Any comments about what Drplokta wrote on his blog about Windows Vista implementing RFC3484 and breaking Round Robin DNS?
It does *NOT* break Round Robin DNS, it breaks the assumption what people make when they setup their DNS in that manner. Slight difference ;)
It's old news - glibc also implemented rfc3484 in getaddrinfo(), which I reported to novell in dec2007, and which was previous reported in debian.
Clients running Vista and where you have a Round-Robin DNS setup where the prefixes are very different will now hit the 'closest' prefix instead of a random one like most implementations of DNS resolvers, that is at first hit, when the connection to the first one fails they will fall back to the next closest one. If you have your hosts on the same subnet you won't notice the difference.
You won't get any load-distribution either.
