What would be some of major use-cases in which you would want to assign multiple IP addresses to your NIC?

Knowing of any standard/well-known 'gotchas' associated with each use-case would also be helpful. For example, I heard someone saying that a user with access to such a machine will automatically get access to both networks, which could be a security issue.

You can assume a Linux-based environment.
