I think the title says it all. I haven't found the answer anywhere else on the internet.

    Sadly, this question shows little or no research. For example, you might look at Wikipedia .

    An IPv4 address is an unsigned, 32-bit number. There are various notations, more or less human-readable.

  • This is just a common way to represent IP addresses that are just a 32-bit unsigned integer. People find it easier to remember 10.0.0.1 rather than 167,772,161 or 0x0A000001. Another layer on top of that is DNS that converts these numbers to meaningful names - e.g. www.google.com

An IPv4 address is an unsigned, 32-bit number. For human readability, it is most often written as four decimal octets, separated by dots, e.g. 192.0.2.253. Any octet can range from 0 to 255 (28-1). Not all combinations represent valid IP addresses.

IPv6 uses 128-bit addresses that are most commonly written as eight 16-bit hexadecimal words (each 0 through ffff), separated by colons. Multiple, consecutive 0 words including their colons can be abbreviated by :: a single time, e.g. 2001:0db8:85a3::0370:7334 for 2001:0db8:85a3:0:0:0:0370:7334.
