Same problem with raspbian stretch and avahi. I used dhcp binding of my router to fix the address 192.168.2.4 to Mac address b8:27:eb:3f:11:5f.
Few hours later, after the syslog gives the "Withdrawing address record for 192.168.2.4" the machine gets another ip-adres, 192.168.2.23 from the dhcp router. Checking in the router to see why it don't bind I see the router assigns 192.168.2.23 to Mac address 86:16:f9:3f:11:5f The first Mac address is right, b8:27:eb belongs to raspberry http://standards-oui.ieee.org/oui.txt The second Mac address starting 86:16:f9 is not known by http://standards-oui.ieee.org/oui.txt. Where does the second, incorrect, Mac address came from? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1586528 Title: Avahi-daemon withdraws address record To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1586528/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
