    This may be off topic for this discussion: tcp/ip question


    I have been from top to bottom with web related dev/programming/server setup and admin:

    In the late 2000's I had static ip addresses for the sake of serving 4 domains
    from home on home built amd 64 servers running FreeBSD, including nameserver configuration
    and postfix mail server set up for the 4 domains.
    So, I have a fair idea of networking issues.
    The tcp/ip rules are that network addresses in the ranges of, and are designated as for private local net
    use and are not served from remote locations ( accept for VPN networks).
    My question is
    What about address ranges from to and to
    (my working knowledge is limited to ip4 addressing)

    These are all ipv4 addresses, but to answer your question, the private network ranges are defined as follows: (what a waste of a class A) (APIPA)

    So doing some bit calculation magic, that would give you these ranges: - - - -

    Anything outside of these ranges are routeable (except you shouldn't work with class D and E address ranges).
    PHP Code:
    header('HTTP/1.1 420 Enhance Your Calm'); 
    Been gone for a few months, and haven't programmed in that long of a time. Meh, I'll wing it ;)
