This bug has been open two years and it's still occurring. I've noticed
it during development of an open-source network security sensor I'm
planning to publish in the next few weeks:

{ "source": "dns", "port_id": 0, "direction": 1, "self": 0, "length":
76, "eth_type": 2048, "smac": "50:e5:49:36:0a:db", "dmac":
"78:96:84:71:ea:c0", "sip": "192.168.1.5", "dip": "192.168.1.254",
"ip_protocol": 17, "ttl": 0, "l4_length": 42, "icmp_type": 255,
"icmp_code": 255, "sport": 37657, "dport": 53, "dns_name":
"daisy.ubuntu.com." }

It's a little unbelievable it's been open this long with no concrete
plan taking shape.

Title:
  Constant dns traffic for daisy.ubuntu.com

Status in Ubuntu error tracker client (whoopsie):
  Confirmed
Status in “glib2.0” package in Ubuntu:
  Invalid
Status in “network-manager” package in Ubuntu:
  In Progress
Status in “whoopsie” package in Ubuntu:
  Triaged

Bug description:
  Watching GNetworkMonitor's network-changed signal causes constant DNS
  traffic.

  Andy Whitcroft points out that the NETLINK_ROUTE socket set up by
  GNetworkMonitor will fire events every time an ARP entry appears or
  disappears.

  Unfortunately, we currently need an additional layer of connectivity
  checking because checking NetworkManager's state for CONNECTED_GLOBAL
  is not enough to know whether we're really online. Ubuntu does not yet
  use the NetworkManager connectivity check [1].

  The likely solution to this bug is a replacement for GNetworkMonitor
  in whoopsie.

  Original report follows:

  Every few seconds, I see a dns query for daisy.ubuntu.com. After
  removing whoopsie, the traffic goes away.
