Hello, we have a SSL cert nearing expire, but it seems that I have to delete it and rescan to make sure no one has replaced it yet. Is there another way to do this? But my main question in, for this cert nearing expire, I deleted it and scanned the IP again. The Common name is always the same but every time I scan, its coming back with a new DNS name to different applications each time I do this. I don't understand this behavior. Can someone explain it? For example, 

I scan 10.10.10.10, it comes back with XYZ.company.com under common but each time the DNS name is different. abc.company.com, efg.company.com, fgh.company.com etc.
