Which IP numbers does clintonemail.com use?
CLINTONEMAIL.COM
uses the IP number208.91.197.27
only which alsoWESTERNLAWN.COM
,SHANKHASSICKFARM.COM
,MAIL.USOPENSHOP.ORG
and more than a million other use.
And indeed WESTERNLAWN.COM resolves to 208.91.197.27, as does clintonemail.com.
Where the server now is, is irrelevant.
Obviously, it needs to be someplace other than where it used to be, or else the Clintons' Netflix would be negatively impacted by all the hacker traffic. DNS is reconfigurable.
