It's the 3rd paragraph.
The article explicitly denies that the Colorado firm hosted Clinton's email service. Read the fifth paragraph:
"Similarly, Platte River Networks is today providing to the Department of Justice the server and related equipment on which emails to and from Secretary Clinton's clintonemail.com were stored from 2009-2013 and which PRN took possession of in 2013," Kendall added.
PRN did not host Clinton's email. They did not take possession of the server until after she left the State Department.
As a matter of fact, I pointedly asked you this question, because I knew that the answer was not PRN. In fact, EXACTLY WHO DID host clintonmail.com, and when they hosted it, is a matter of serious concern.
Examining the “IP address history” of clintonemail.com, Webster concluded there was “strong evidence” that Clinton’s domain had been hosted by two successive private-sector firms: ThePlanet.com, now known as SoftLayer and acquired in recent years by IBM; and Austin-based Confluence Networks, which Webster describes as “a hosting firm of very, very dubious provenance and management, to say the least.”
Read this article, and understand why the chain of possession is important:

The truth is, we do NOT know where the server was hosted while it was storing, accepting and forwarding the most sensitive information, even at this very late date.
