What you seemed to suggest was, "don't use DNS" without giving any reasonable alternative. That isn't really productive either :-) > I haven't switched to IPv4 because > the IPv6 resolver took a couple of extra roundtrip times. The extra roundtrip times are just the tip of the iceberg. Consider broken DNS servers, load balancers etc. out there -- which may eat your AAAA query for e.g. 10 seconds, causing a lot more delay than a couple of roundtrips. > I see another way of fixing: > > If this option is problematic, don't use it.

As for AI_ADDRCONFIG, it's maybe not used because it hasn't really been implemented that much, maybe because it has been specified in a rather useless way (and it requires a proprietary interface between the glibc and kernel to get the addresses, such as the getaddrinfo destination address ordering as well; dst addr ordering hasn't been implemented that much either).. > You will have to give me other arguments to kill the on-link assuption.
