Understanding IP Addresses
Before we dive into the steps to find your Mac’s IP address, it’s crucial to understand what an IP address is and its significance in networking. An IP address, or Internet Protocol address, is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol to communicate. IP addresses serve two primary functions: they identify the host or network interface and provide the location of the host in the network, allowing data to be routed across the internet.
There are two main types of IP addresses: IPv4 and IPv6. IPv4 addresses are 32-bit numbers, typically expressed in dotted decimal notation (e.g., 192.0.2.1), while IPv6 addresses are 128-bit numbers, usually written in hexadecimal notation (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). Most networks still use IPv4, but IPv6 is becoming more prevalent due to the increasing number of devices connecting to the internet.
