    AAAA DNS Records Now Carry Random Numbers

    AAAA DNS Records Now Carry Random Numbers

    "He also stressed that industry needs to ensure that communications technologies have built-in security protections."

    Many of the new Internet technology innovations
    are coming from the proven Banking Industry.
    For years, the Banking Industry has developed
    techniques for helping to ensure that transactions
    are secure, private, etc. One way to do that is
    with encryption but another way is with chaos
    and randomness, where only the legitimate parties
    can deduce the correct results from the chaos.

    The 128-bit DNS AAAA (quad-A) Records are ideal
    for sending a large random number along with
    the existing A Records. Old systems just ignore
    the AAAA Records, more modern systems can store
    the 128-bit binary value and use it in end-to-end
    transactions. When appended to time-of-day values
    the random value can be used to provide sub-second
    distinctions to help keep transactions unique.
    The 128-bit values can also be used by two parties
    when contacting a common third party, as a key
    to show they queried the same DNS system.

    Multiple A Records are of course used to expand
    the addressing beyond 32-bits. The AAAA Records
    are used to enhance the security and stability
    of the connections and transactions.
