Added info...

The icmp6_send events seems to coincide with the DNS queries to
daisy.ubuntu.com. I'm not quite sure why the kernel is complaining about
IPv6 stuff, as it is working just fine. Connecting to
https://www.v6.facebook.com/ and https://ipv6.google.com/ come up with
no problem using the IPv6 tunnel I mentioned in my previous post.

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.

  pluckers/whoopsie/trunk/view/head:/src/connectivity.c#L326

  Original report follows:

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