With r285550, more of the IPv6 can be seen, but the problem remains, that it
displays IPs only for hostnames that return only one IP on reverse lookup.

Thanks for the explaination. Apparently the man page needs a fix, or the
whole concept needs to be fixed 8-(

w does only lookup the IP if there is only one A/ record. if there are
multiple records (this means A and A or  and  but also A and ), the
lookup is bypassed. You may further call this an IPv6 unawareness of some kind,
if there is exactly one IPv4 and one IPv6 entry.

The cause of this is the usage of utmpx. Which means there is only a hostname
in the database, no ip address.

You are stranded if you do not have access to the underlying protocol family or
have multiple A/-Records. The user MAY be connected via a totally different
IP/Machine instead the IP displayed. So the current strategy is: instead you
display wrong data, you display the original data unresolved. 

In fact I believe this is exactly the point why other implementations are
missing this parameter.
