[Bug 1586528] Re: Avahi-daemon withdraws address record

[Sander van der Stap]

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?

Title:
  Avahi-daemon withdraws address record

Status in avahi package in Ubuntu:
  Confirmed
Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  For some reason, if I leave my Ubuntu VM up for a prolonged period of
  time the machine will lose connection to the network.  ip addr shows
  that the nic port no longer has an address and an examination of the
  syslog shows this:

  May 27 14:19:38 matt-VirtualBox avahi-daemon[590]: Withdrawing address record for 10.0.2.15 on enp0s3.
  May 27 14:19:38 matt-VirtualBox avahi-daemon[590]: Leaving mDNS multicast group on interface enp0s3.IPv4 with address 10.0.2.15.
  May 27 14:19:38 matt-VirtualBox avahi-daemon[590]: Interface enp0s3.IPv4 no longer relevant for mDNS.

  
  for no known reason.

  The only reliable way to get the network to come back (that I have
  found) is a full reboot.
