Learn more on WikipediaAn IP address, or Internet Protocol address, is a unique string of numbers assigned to each device connected to a network, such as the Internet. It allows devices to identify and communicate with each other by providing an address for sending and receiving data. There are two types of IP addresses: IPv4, which consists of four sets of numbers, and IPv6, a newer version with a longer address format to accommodate more devices. An IP address is essential for browsing the web, sending emails, and using online services.

- VPNs mask users' IP addresses to protect their online privacy and anonymity.
- Dynamic IP addresses are assigned by ISPs and may change periodically.
- IPv6 expands the pool of available IP addresses to accommodate the growing number of Internet-connected devices.
