The unique IP address of a website hosting server consists of numbers because an IP address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. This numerical address is made up of a series of digits, typically formatted as four groups of numbers separated by periods in IPv4 (e.g., 192.168.1.1) or as eight groups of hexadecimal characters in IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). The numbers in an IP address serve the crucial role of identifying and locating the device on the network, enabling communication between computers and servers.

Other types of content such as letters, words, images, or videos do not form the basis of an IP address. Those elements can be part of what a website offers or displays after it is reached via the numerical IP address, but they do not comprise the address itself. Therefore, understanding that the structure of an IP address is numerical is essential in the context of how devices communicate over the internet.
