Dot-decimal Notation

Dot-decimal notation, also called Dotted decimal notation or dotted quad notation, is a method of writing down octet strings using base-10 (decimal) rather than hexadecimal numbers. Adding dots allows for easy separation of the individual octet values. For example, 255.255.255.255 is in dotted-decimal notation. IPv4 addresses are almost universally written or typed in dot-decimal notation.
