Loopback Interfaces

From a design & management standpoint, what is the best practice for assigning IP addresses to Loopback interfaces? i.e., should they always be in the same subnet as your physical interfaces? Our production network doesn't follow this philosophy and I'm wondering if there is a reason for it.

    Me personally (opinions will vary), I use loopbacks and assign them a "host" address. Meaning I'll assign them an IP of a private network with a mask of all 255. If I need that loopback to be reached by other devices on my LAN, I'll add it to my routing protocol. This link provides some design ideas that may assist you. HTH.
