Dot-decimal notation is a presentation format for numerical data. It consists of a string of decimal numbers, using the full stop (dot) as a separation character. [1]A common use of dot-decimal notation is in information technology where it is a method of writing numbers in octet-grouped base-10 numbers. [2]
Any such symbol can be called a decimal mark, decimal marker, or decimal sign. Symbol-specific names are also used; decimal point and decimal comma refer to a dot (either baseline or middle ) and comma respectively, when it is used as a decimal separator; these are the usual terms used in English, [ 1 ] [ 2 ] [ 3 ] with the aforementioned ...

Decomposition of an IPv4 address from dot-decimal notation to its binary value. An IPv4 address has a size of 32 bits, which limits the address space to 4 294 967 296 (2 32) addresses. Of this number, some addresses are reserved for special purposes such as private networks (≈18 million addresses) and multicast addressing (≈270 million ...
That is, fractions of the form a/10 n, where a is an integer, and n is a non-negative integer. Decimal fractions also result from the addition of an integer and a fractional part; the resulting sum sometimes is called a fractional number. Decimals are commonly used to approximate real numbers.
They are most often written in dot-decimal notation, which consists of four octets of the address expressed individually in decimal numbers and separated by periods. For example, the quad-dotted IP address in the illustration ( 172.16.254.1 ) represents the 32-bit decimal number 2886794753, which in hexadecimal format is 0xAC10FE01.
