Locating a specific website in this vast library can be challenging. To address this problem, the user's browser sends a message to their Internet service provider (ISP) requesting access to a particular website, such as google.com.

The ISP then forwards this message to a DNS server, acting as a phone book, which then searches its database for the IP address of the website. The IP (Internet Protocol) address is a unique identifier for every computer connected to the Internet, like a postal code. Once the DNS server locates the IP address, it sends it back to the user's browser via the ISP. The user can request to access the website directly via the IP address, and the servers will provide all the necessary files and data to access their homepage.

Undersea cables connect all the continents, enabling Internet communication. The cables transmit up to 400 gigabytes of data per second. Despite the complexity of the Internet's infrastructure, all that is required to access a website or web app is an IP address.
