grab the nameservers from the whois.
In this case:
server ns1.msft.net (etc.)
In this case ns1.msft.net doesn't even answer consequently
you will not be able to get any addresses for the other domains.
If you query your local isp dns (or google at 126.96.36.199 or 188.8.131.52) it's
possible they have the addresses cached and will return something.
But if the dns isn't answering (per the whois) you have at
the very least a dns issue.
While I was typing this ns1.msft.net started to answer again...when
I started the "server ns1.msft.net" part failed.
