  Not even necessarily the host.  Firefox, for example, has its own setting 
for whether or not to look up IPv6 addresses.  (This can cause a problem 
with dual-stack setups when the IPv6 address for a record is inaccessible 
or firewalled; the attempt has to time out before Firefox tries the IPv4 
address.)  For the record, this behavior can be changed via about:config, 
under "network.dns.disableIPv6" (just type "ipv6" into the filter box).
