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)

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?
think a little bit deeper in it, it seems that iftop is doing strange things, other than described in the issue , there are NO succesfull lookups of ipv6 addresses other than etc/hosts .. and there it picks randomly (i guess the first occuring of) a hosts-entry for a ipv6 and from this moment on use it buggy-wise use this for all ipv6 which are there ..
dont know if that helps in finding the problem, just wanted to clear this
