This sounds like exactly the behaviour that I explained in 2013 here: https://askubuntu.com/a/332421/7808
ifconfig still exists but is deprecated and no longer shipped by default. Users should use its replacement "ip" instead. However it is true that ifconfig does not display the additional aliases set by ifupdown, so the bug remains valid. But since ifconfig is deprecated we don't expect this to ever be addressed, so I'm setting the bug status to Won't Fix. ** Changed in: net-tools (Ubuntu) Status: Expired => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/878333 Title: ifconfig not showing virtual ip addresses To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/net-tools/+bug/878333/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
