URL vs. IP Address — What's the Difference?

URLs (Uniform Resource Locators) and IP Addresses are fundamental concepts in the realm of the internet and networking. A URL is a specific character string that constitutes a reference to a resource on the internet. It's like the address of a specific webpage or file online. An IP Address, on the other hand, is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for a network or device.

URLs are designed to be easily readable and remembered by humans. They often include a domain name that is intuitive and represents the entity behind the website. IP Addresses are more technical and are used primarily by computers and networking equipment to route information. They consist of a series of numbers, which can be difficult for humans to remember.

The structure of a URL can include various components such as the protocol (like HTTP or HTTPS), domain name, path, and query parameters. This structure helps in navigating and accessing specific content on the internet. An IP Address is structured as a series of numbers separated by periods (in IPv4) or colons (in IPv6). This structure is integral to the underlying technology of the internet, ensuring accurate data transmission between devices.

While URLs are used to locate web resources, IP Addresses are used to identify the network or device through which these resources are accessed or delivered. In other words, a URL takes you to a specific destination on the internet, whereas an IP Address identifies each stop along the way.

URLs can be changed or redirected as needed. For example, a website can change its URL while maintaining the same content. IP Addresses can also change, especially with dynamic IP addressing in home networks, but each IP must remain unique within its network to avoid conflicts and ensure proper network communication.
