$ for i in `dig a www.ebay.com +short | grep -v www` ; do printf "%-32s%-20s" "`date`" "$i" ; curl -i -s -S -H "Host: www.ebay.com" http://$i/ >/dev/null ; echo $? ; done
Wed Jan 22 22:32:52 PST 2014 66.211.181.181 0
Wed Jan 22 22:32:52 PST 2014 66.135.200.161 0
Wed Jan 22 22:32:53 PST 2014 66.135.200.181 0

Wed Jan 22 22:32:55 PST 2014 66.211.181.161 0
In English: I have no trouble getting back HTTP content from any of
those IPs, and promptly.
Source IP is 76.102.14.35, located in Mountain View, CA.
