Description Alexander Bokovoy 2017-04-10 07:20:07 UTC 
There are still areas where internal DCE-RPC connection implies presence of IPv4 stack and addresses. This wouldn't work in pure IPv6 configuration.

Comment 1 Björn Jacke 2021-02-26 14:39:06 UTC 
we should ask getnameinfo for the IP address of localhost, a reasonalby well configured systems will either return 127.0.0.1 or ::1 and we should connect to whatever we get back there, right?
