For what it's worth - I am seeing (I believe) this same issue on the latest Kali linux:
https://bugs.kali.org/view.php?id=7116 What's very interesting is that after this race condition happens, the machine still responds to the old IP yet it doesn't show with 'ip addr show'. Seems to be something down in the kernel that is still claiming this old IP. ** Bug watch added: bugs.kali.org/ #7116 https://bugs.kali.org/view.php?id=7116 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1793763 Title: NetworkManager interaction with dhclient triggers IP conflict detection at dhcp server, causes ip address changing every day To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1793763/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
