How many internet-connected devices do you own? If you took a quick inventory around your house, you may be surprised at exactly how many there are. Have you ever wondered how they all communicate, not only with each other, but with the internet as well? This is, in part the result of technology known as IP addressing.
What is an IP address?

Just as your home has a postal address, a unique IP address is assigned to every device on the internet, serving as an identifier for your system, allowing the ability for communication over a network. A protocol is the set of rules that govern the structure and function of the addressing scheme. Just as there are rules for interacting with others in a social setting, IP addressing

There are mainly two versions of IP addressing, IPv4, and IPv6.
Internet Protocol version 4 (IPv4) is the older version of IP addresses which uses a 32-bit format allowing 232 or approximately 4.3 billion unique IP addresses. Each IPv4 address is made up of 4 sets divided into octets separated by a period, containing decimal values between 0 and 255. For example, 1.2.3.4, or 192.168.1.1 and all combinations up to 255.255.255.255.
With increasing numbers of devices connected to the Internet, the 4.3 ..
