That's more because "-s ." is a replacement for "-s a.root-servers.net".
It even breaks if you do "-4 -s .", where -4 stands for "use only

Tracing to www.mavetju.org[a] via a.root-servers.net, maximum of 3 retries
A temporary work-around is to use "-s b.root-servers.net" so that
the second issue is overcome.
The real issue here is though:
"doesn't work on IPv6-capable hosts with no global IPv6 routing".
That's the same as complaining that you can't real www.$somesite
when you don't have global IPv4 routing.
