What's the history behind 192.168.1.1? Why not 192.169.1.1 or any other IP address? When did it start being used? Who started it? Why? Why not 1.1.1.1? What is the relation to 127.0.0.1? What about 10.0.0.1 (Apple)?

    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:

    • 10.0.0.0/8 IP addresses: 10.0.0.0 -- 10.255.255.255
    • 172.16.0.0/12 IP addresses: 172.16.0.0 -- 172.31.255.255
    • 192.168.0.0/16 IP addresses: 192.168.0.0 – 192.168.255.255

    So '10.0.0.1' 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.

    127.0.0.1 is another story. In RFC-1122 (1989) 127.0.0.0/8 is designated as loopback address range. So they can only point to the host itself.
