Phishing Name Server?

The Internet Storm Center [http://isc.sans.org/diary.php] is
reporting that:

"The DNS server 'NS1.SPX2K.com' currently hosts the following
domains CITIFINANCUPDATE.com, SAFE-KEYNET.com, WAMU4U.com,
WAMUCORP.com which appear to be phishing related. The use
of actual 'valid' domains like this opens up the possibility
that they are used with SSL certificates. The whois info for
these domains appears to be fake."

Does anyone have any further information into this?
