    IPv6 addresses are hexadecimal so we count from 0 to F. There is no “hexadecimal 10” so be aware not to read it as a decimal 10, it’s a one and zero.

    The first part (2001:41f0:4060:) is the same so let’s ignore that. Let’s look at 1 and A in binary:

    1 = 0001
    A = 1010

    Hope this helps!

  5. Hello Brian

    Yes, I understand your concern. After spending years (and some of us decades) learning and understanding IPv4 with both its strengths and its limitations, it is very often hard to avoid viewing IPv6 in a similar manner.

    Now if you have a prefix length of 48, 64 or even 96 bits which are all very common in IPv6, then of course you will have a subnet capable of supporting an ridiculously enormous number of hosts. Although IPv6 can actually handle a greater number of hosts per subnet than IPv4 (because there are no broadcasts and because it handles a
