Hi Charles. What version of 'host' are you using? The output above is
not that I'd expect from a vanilla host command. Do you have aliases set?
You may wish to consider using 'dig' too.
The domain looks fine to me. The SOA TTL is arguably too short.
Notice I query authoritative servers below.
$host -t ns ishares.com
ishares.com NS ns2.barclaysglobal.com
ishares.com NS ns1.barclaysglobal.com
