See also https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=952740 and these maybe-related glibc bugs: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=780294 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=455762 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854301 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=854302 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=897662 #952740 has some more references. > glib2.0_2.64.3-1 I'm surprised GLib 2.64.x is affected, because GLib since 2.63.1 has implemented the Internet-Draft <https://tools.ietf.org/html/draft-ietf-dnsop-let-localhost-be-localhost-02>, which I believe is also implemented in the major web browsers, and should have made it bypass the issues that prompted me to open #952740. (But perhaps something different is happening here.) Older GLib versions (in buster and older) are unlikely to be fixed. As I said on #952740, I don't think it's particularly scalable for every consumer of the getaddrinfo() API (or at least those that want to resolve and talk to localhost in their unit tests) to have an independent reimplementation of <https://tools.ietf.org/html/draft-ietf-dnsop-let-localhost-be-localhost-02>, so it would be great if glibc could solve this for all of us at once. smcv
