perhaps it timed out - your nameservers might be slow to provide the
answer...

ping www.yahoo.com
nslookup www.yahoo.com
ping www.yahoo.com

service nscd restart
ping www.yahoo.com
nslookup www.yahoo.com
ping www.yahoo.com

I've had a bunch of problems with speed of dns with ipv6 and have
resorted to doing...

echo "alias net-pf-10 off" >> /etc/modprobe.conf

and rebooting to turn it off
