Summary: When a link-local IPv6 address is configured name resolution fails. The lookup / connection times out Steps to Reproduce: 1. Configure only a link-local IPv6 DNS server 2. Try to resolve a hostname Expected Results: The hostname to be resolved Actual Results: The lookup times out Regression: Notes: In my case the link local IPv6 address is provided by the RA via RDNSS. I guess that the OS X resolver fails to determine the interface to use for the lookup. When i have my radvd advertise the global IP of the DNS server it works fine. Manually performing a lookup with 'dig' against the link-local IP also works fine, if the interface is specified (IP%en0).
