Iftop ipv6 bug ?

Is there an issue with iftop & ipv6 lookups

Was just checking out the bandwidth i was using with my Apple TV and noticed it was displaying ipad.localdomain rather than bedroom-atv.localdomain.

When I hit "N" to display the ip address rather than the hostname it displays the correct IP (:35) address for the device.

Did you try a reverse lookup on :35? Odds are iftop doesn't have a bug, it's just what that IP address reverse-resolves to.

Yup tried a nslookup, they are different addresses, I converted the last portion of the IPv4 address to hex and used that for the IPv6 address :-
