Root name servers or GTLD name servers? It is quite different. Let's
assume you talk about the ".com / .net" name servers,

They work fine with IPv6 so I'm not sure why you want to disable
it. If you have no IPv6 connectivity, just do not enable IPv6 in your
kernel (on Linux, do not load the IPv6 kernel module, see /etc/modules
and /etc/modprobe.d/aliases).

The strongest test, if you do not believe --disable-ipv6, is to run
'tcpdump -n ip6' on the resolver and to check that there are no IPv6
