What is the difference between an IPv4 and IPv6 address?
IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6) are two different versions of the Internet Protocol used to assign IP addresses to devices on a network. IPv4 addresses are 32-bit addresses, typically written in dotted decimal notation (e.g., 192.168.1.100), while IPv6 addresses are 128-bit addresses, typically written in hexadecimal notation (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
The main difference between IPv4 and IPv6 addresses is the address space. IPv4 addresses are limited to approximately 4.3 billion unique addresses, while IPv6 addresses offer a virtually unlimited address space. As a result, IPv6 addresses are becoming increasingly common, especially in modern networks and devices. Your MacBook may have both an IPv4 and IPv6 address, depending on the network configuration.
