00000000F0

00000000F0 is a 12‑digit hexadecimal literal that represents the 48‑bit value 0x00000000F0. The left‑hand zeros are often used to provide fixed‑width formatting, ensuring that the string remains 48 bits long even though the significant part of the value is only the low‑order byte 0xF0. In binary this byte is 11110000, which can be useful as a mask for clearing or setting the four most significant bits of a data word.

In computing literature, 00000000F0 is used primarily as an example of a padded constant. For instance, it may appear in documentation describing how to construct memory addresses, where the full 48‑bit address space of some systems is shown in its widest form but only the lowest byte varies. It also shows up occasionally in instruction manuals that illustrate bit‑field manipulation: a 0xF0 mask is applied to a register to isolate or clear the high nibble while leaving the low nibble untouched.

In the realm of network hardware, 00000000F0 can be seen as a placeholder MAC‑address suffix or a default device identifier in configuration files. In graphical contexts it can be interpreted as an ARGB colour code, where the alpha, red, and green components are zero and the blue component is 240 (0xF0). This yields a very dark blue colour with full transparency when the alpha field is interpreted in the usual manner.

Although it does not correspond to a widely adopted standard value, the pattern 00000000F0 is useful in examples and teaching materials because of its clear structure and the simplicity of the underlying bit pattern.
