avahi-daemon: Withdrawing address record for IPv6 on wireless

splurben · 2015-12-28 05:51:33

Hey y'all,

Here's a funny one that I can't find a lot of information about in searching.

At random intervals between 5 and 10 minutes I get copious messages from systemd about the avahi-daemon and the wireless interface on one system (wlp2s0). It seems to be mainly IPv6.

Here are the messages:

Is this to be expected? The wireless and Internet router is Apple Airport Express with IPv6 set to Automatic.
