if you delve in to the glibc resolver code I believe it does a ipv6
lookup first (type AAAA), you can check this, in another window do
tcpdump -pni eth0 port 53 -vv
and in another window try wget www.facebook.com -O /dev/null
you should see a request for a AAAA record and then a A record.
ipv6 will auto configure an address, but shouldn't configure any routing
unless it has been enabled on the network. have a look at ip -6 r and ip
If you don't need ipv6 then turn it off
