I had a weird issue the other day and was hoping someone could explain how to dig in a bit deeper to find the destination of a flow.
When I brought up the top Endpoints page and filtered for a certain time period, I got most of my normal high bandwidth hosts, but the top host was a period followed by a colon, ".:" I'll call this the mystery host for now.
Looking at the other hosts it is usually their DNS entry followed by the ip address in parenthesis and a colon, ie. "awesomewebsite.com (8.4.1.20):"
Clicking on the mystery host brings up the same screen. I'm wondering if this period is a DNS hostname or maybe a bug? How can I tell? Example pic below.
