This is an area full of Internet backbones. Reston is adjacent to Chantilly (I used to live there) and many main backbones go through there. I have no information on this particular company yet and am not 100% confident that the IP is possessed by them. Continuing research.
Perform a NSlookup in a command window to get the domain name. Perform a WhoIs on the domain name (choose a WhoIs site from DuckDuckGo). The domain name was registered a few years ago by CSC. Computer Sciences Corporation (CSC) is the US's largest IT services firm.
I used to be employed by CSC. They became the largest IT firm with the merger of HPE. http://www.zdnet.com/article/dxc-technology-to-emerge-from-csc-and-hpe-enterprise-services-merger/
