IPv4 address formats

An IPv4 address can be represented in different number systems. The familiar dotted decimal notation (e.g. 192.168.1.1) is just one of many formats. In networking and programming, hexadecimal (e.g. C0.A8.01.01) and decimal (32-bit integer) formats are commonly used. The binary representation shows the actual bit structure, which is important for understanding subnetting and network masks.
