What do the four numbers in an IPv4 address actually mean? Think of a phone number: splitting it into chunks makes one longer number easier to read. IPv4 follows a similar idea. An IPv4 address is one 32-bit number, written as four decimal pieces. In 192.168.1.10, those pieces are 192, 168, 1, and 10. Each piece is an octet-an 8-bit section. The dots simply separate the sections in the written format. They do not divide four separate addresses. Every octet must be a decimal value from 0-255. So 192.168.1.10 is an example of the format, not necessarily your address. Read it as four bounded pieces, kept in order, working together as one address. So what do those four numbers mean? They are four 8-bit pieces, each from 0-255, written with dots, and together they form one 32-bit IPv4 address.
