I tried reproducing this bug hoping to be able to fix it but had a little bit of trouble reproducing it. From what I can see on RELENG_7 and RELENG_6 the -n flag will work the same way for IPv4 and IPv6. In the case that -n is set w(1) just reads from /var/run/utmp and basically dumps the address that's written there.
On my machine I'm seeing IPv6 addresses being written into /var/run/utmp and w(1) is working as designed. If I ssh to ::1 or 127.0.0.1 then localhost is written to /var/run/utmp and `w -n` prints localhost even though I said -n.
I'm wondering if you can share part of your utmp file to verify that the hostname is being written in to that file rather than the IPv6 address?
If there is a bug here I believe that it's in whatever writes to /var/run/utmp, not w(1).
