When talking about unnumbered interfaces, you're mostly/only
talking about routers.
IP allows you to configure a point-to-point  connection without using an IP address, this could save you some IP address. These unnumbered interfaces must be associated with a numbered interface on your router. This is typically used to give the PPP and Ethernet interface the same IP address. All routers IOS support unnumbered interfaces. You don't need to enable anything on your IP stack
