===Memory address identity===
A trivial but pervasive example of perfect hashing is implicit in the (virtual) [[Virtual Memory|memory address space]] of a computer. Since each byte of virtual memory is a distinct, unique, directly addressable storage ___location, the value of the (starting) [[Pointer_(computer_programming)|address of any object]] stored in memory can be considered a ''de-facto'' perfect hash of that object into the entire memory address range.{{cn|date=March 2022}}
