ZNC claims that ::1 is listening also on IPv4 and 127.0.0.1 also listens on IPv6 which makes no sense. If it in reality doesn't do that, ZNC should automatically adjust what it shows to the user.

  • Debian GNU/Linux 7.9 (wheezy)
  • ZNC 1.7.x-git-397-2c0dfbb - http://znc.in
    • IPv6: yes, SSL: yes, DNS: threads, charset: yes
