if i use v6 inside this wireguard tunnel .. so the IPs are more like fdf1::16:3e75:72af (/64) than there is only one ip shown all the time - or one dns entry (from /etc/hosts)

but strangely iftop get the streams right ... so i have plenty of connections from fdf1::16:3e75:72af to fdf1::16:3e75:72af

they all show the correct amount of traffic, but the naming/display "error" makes it difficult to use or understand whats going on.

This is a long standing bug. Here is when I reported it for RedHat:

https://bugzilla.redhat.com/show_bug.cgi?id=1120254

The workaround is to turn off DNS lookup ('n'). DNS is unreliable anyway, right?
