Understanding IP Addresses
Before diving into the process of changing your WiFi IP address, it’s crucial to understand what an IP address is and how it functions. An IP address, or Internet Protocol address, is a unique set of numbers assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses serve two primary functions: they identify the host or network interface and provide the location of the host in the network, enabling devices to communicate with each other.
Types of IP Addresses
There are two main types of IP addresses: IPv4 and IPv6. IPv4 uses 32-bit addresses, which are typically written in dotted decimal notation (XXX.XXX.XXX.XXX), whereas IPv6 uses 128-bit addresses, written in a more complex format. Most home networks and many online services still rely on IPv4, although IPv6 is gaining more traction due to its ability to provide a much larger number of unique addresses.
Dynamic vs. Static IP Addresses
IP addresses can be either dynamic or static. Dynamic IP addresses are assigned automatically by your internet service provider (ISP) and can change each time you connect to the internet. This is the most common type for residential users. Static IP addresses, on the other hand, are manually assigned and do not change. They are typically used by businesses, web servers, and individuals who require a constant IP address for their operations.
Why Change Your WiFi IP Address?
There are several reasons you might want to change your WiFi IP address on a Mac. Some of these reasons include:
