I don't think anyone designs anything specifically for loopback. Certainly there are cases where for security reasons you only have a service running on the loopback interfaced and lots of other situations where you can use the loopback interface in a novel or interesting way, but this is just an abstraction and nothing more...it can be whatever you want it to be. > Ever use **multiple** addresses in 127.0.0.0/8 block > simultaneously???
