Title:
  Suspend/Resume cycle changes advertised hostname (loss of name
  resolution)

Status in avahi package in Ubuntu:
  Confirmed

Bug description:
  On 16.04 and 18.04 hosts on my LAN I've been suffering intermittent
  loss of mDNS resolution after devices have been suspended and resumed.

  Today I decided to investigate and noticed that on resume the hostname
  being advertised is changed.

  E.g.

  hephaestion.local == Cold Boot
  hephaestion-1.local == 1st suspend/resume
  hephaestion-2.local == 2nd suspend/resume
  ...
  etc.

  It can be reset by restarting the service:

  systemctl restart avahi-daemon
