It was /etc/nsswitch.conf that contained new (odd) entries!
It's solved, I knew I had to share this to solve my issue.
Thanks for the conversation!

I just checked my system with a tcpdump to catch all DNS messages and I find that the host never tries to resolve its own IP addresses when iftop is started (but of course I get a ot of DNS queries for the connected peers, and they are valid as public DNS PTR records). So I should definitely check on my system why it's not even trying to resolve these "considered local" IP addresses using DNS.
But I'm stuck because I'm not sure where I should look.

Hello Paul,
Yes, I have the correct IP addresses when I turn off resolution.
