This is done in in sysdeps/unix/sysv/linux/check_pf.cl line 179, in make_request().įor what it's worth, both Microsoft Windows and Mac OS X appear to disregard link-local IPv6 addresses for AI_ADDRCONFIG purposes, with no apparent ill effects. And, as it happens, loopback addresses are already disregarded by getaddrinfo() for AI_ADDRCONFIG (even for IPv4 loopback addresses). In that regard link-local addresses are very similar to loopback addresses, in the sense that they're automatically configured on all hosts regardless of any external connectivity, and can not be used when communicating with the outside world. While it does not mention link-local (or loopback) addresses specifically, it is obvious that its intended use is to allow an application to avoid getting addresses returned that cannot be used for communication. If the node has at least one IPv4 source address configured. Should occur only if the node has at least one IPv6 sourceĪddress configured and a query for A records should occur only

The AI_ADDRCONFIG flag specifies that a query for AAAA records

RFC 2553 says the following about AI_ADDRCONFIG: This defeats the purpose of AI_ADDRCONFIG, as an IPv6-capable operating system (which includes all modern GNU/Linux distributions) will automatically configure link-local IPv6 addresses on every interface. If the system is configured with link-local (and loopback) IPv6 addresses only, getaddrinfo() will look up AAAA records in DNS and return any results to the caller, even if the caller is specififying the AI_ADDRCONFIG hint.
