Looking more closely, the last 64 bits seem to be zeroed - connecting to
something that has lots of f's...

src/openvpn/openvpn --comp-lzo --verb 3 --dev tun --proto tcp6-client \
	--remote 2001:608:5:ffff:ffff:ffff:ffff:ffff --port 51194
...

mp 1697332759 0>

And it's not related to DNS itself, just to getaddrinfo() (so you don't
need to muck with DNS or setup a tcp6 test server to see this)

If family permits, I'll try to dig into this more tomorrow, it certainly
raised my curiousity :-)
