If you're hitting an IP directly, it most likely means that someone is rehosting the webpage on your behalf, and likely has a list of "runners" at different IPs that will do this. It doesn't really mean anything else though, as all domains eventually translate to IPs anyway.
eg. http://45.55.112.11 will redirect to this domain, but we could've chosen to have it be a standalone web page with no domain name as well.
