I remember first hearing about IPv6 back in the early 2000's.  The argument was: the world is running out of IP addresses (ie, IPv4)!  We can only have 4 billion IP addresses at once, which decades ago seemed fine, but now we can easily envision running out.

So, the powers that be created IPv6.

Instead of IPv4 addresses which look like this:  201.153.26.8

We get addresses like this: 2b81:4708:df30:eeb1:d55f:686c:30a9:e31a

Which are hideous, fill me with rage, and makes it almost impossible to just memorize or write on a sticky note or tell someone over the phone.

But-- I have a solution!

First of all, IPv6 is really a 128-bit number, which is ludicrously huge!  Using IPv6, if you had a dollar for every IP address, you'd have $11,000,000,000,000,000,000,000,000,000,000 dollars.

So-- let's instead use a 64-bit number!

That's still 18.4 quintillion addresses! If a new static and unique and permanent IP address is consumed every nanosecond, it would take almost 600 years to run out of IPs.

A random example 64-bit IP look like:

    cb1e:5b4d:da55:691b

Much easier to type or write or speak over the phone already!

Next, use base-36 for us dumb humans, and add in an arbitrary "." or space or dash every 4 or 5 characters. It all gets converted back to an int anyway so what does it matter?

So the same address now becomes:

   3361-zuvmh-f7hz
or
   336.1zu.vmh.f7hz
or
   33 61 zu vm hf 7hz

In my opinion, it's much easier to remember, write on a post-it note, speak over the phone, etc.

In short, I'm old and hate IPv6.
