Exact same issue. Ubuntu 16.04 LTS 64 (latest updates).
Evert 2-3 days this box is offline? Why? Any fix for this? Ty.
Can be DDoS or random disconnects from avahi, IPV6 or from other scripts?

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.
