    According to standards set forth in Internet Engineering Task Force (IETF) document RFC-1918, the following IPv4 address ranges have been reserved by the IANA for private internets, and are not publicly routable on the global internet:

    • IP addresses: --
    • IP addresses: --
    • IP addresses: –

    So '' is not Apple, it's just that Apple by default uses a different router address than most other router builders.

    RFC-1918 is written in 1996, so that's when it started, or at least when a common habit became standardized. is another story. In RFC-1122 (1989) is designated as loopback address range. So they can only point to the host itself.
