No, a domain cannot be negative. In mathematics, the domain of a function is the set of all possible input values (independent variable) for which the function is defined. The domain can include all real numbers or a subset of real numbers, but it cannot include negative numbers or other non-real numbers, unless the function is specifically defined to allow them. For example, the square root function is only defined for non-negative real numbers, since the square root of a negative number is not a real number.
Similarly, in the context of internet domains, domain names are strings of characters used to identify a specific website. Domain names cannot have negative values. The domain name system (DNS) uses a hierarchical structure to map domain names to IP addresses, which are numerical values that represent a computer or network connection.
