0x1F30AE2

0x1F30AE2 is a hexadecimal string prefixed with 0x. In computing, the 0x prefix denotes hexadecimal notation, and the digits that follow—1, F, 3, 0, A, E, 2—are hexadecimal characters. With seven hex digits, the value contains 28 bits of information.

The string is commonly encountered as a compact identifier in software systems, such as a key in a demonstration dataset, a short resource identifier, or a placeholder in documentation. It is not a standard length for many cryptographic addresses or hashes (for example, Ethereum addresses use 40 hex characters after 0x, and typical hashes are 64 or more hex characters). As a result, 0x1F30AE2 is usually interpreted as an alias or index rather than a cryptographic token.

Storage and handling: such a value can be stored as text in databases (VARCHAR) or as an integer type if the system converts the hex to a binary form. The numeric value ranges from 0 to 268,435,455. When used as a secret or authentication token, its short length makes it unsuitable for security purposes; longer, cryptographically random tokens are recommended.

Origin and usage notes: the 0x prefix signals hexadecimal encoding in many programming languages and environments, including JavaScript, Solidity, and C-family languages. Because it is short and not tied to a known standard, its interpretation depends on the surrounding application. See also hexadecimal notation, 0x prefix, and identifiers in computing.
