An IP address is a set of four numbers that identifies a device on the internet or a local area network. These four numbers are separated by period $(.)$ when written in decimal representation. The four numbers are whole numbers limited from $0$ up to $255.$ An IP address is valid if it consists of four numbers $($limited from $0$ up to $255)$ with periods in between $($e$.$g$.,192\mathrm{.}168\mathrm{.}0\mathrm{.}1).$ Develop a function that will return a tuple of valid IP addresses in a given text.
