I would agree, the knowledge required to setup and multihome with BGP is not
something that everyone in mass will just know.  I have helped many smaller
ISP's with BGP issues, as it's just not something that everyone learns.  So
this alone would keep every joe from a /24, or I would think..

I would have to agree with that, I can't tell you how many times I have seen
stuff setup just to fake need for space, just to meet a larger qualification.
It's without a doubt not that hard to do, and if they are going to go through
the issue of faking a larger layout and getting space anyway, I could see the
reasoning behind putting a /24 out there and saving a lot of wasted space.

There is an amazing amount of wasted IP space allocated, as much as many would
curse over it, there is a real need to go back and require pre-ARIN
allocations to be shown to be used, or justified as what would be reclaimed I
am sure would be astounding.  

I know of /16's that are just totally unused, some that weren't even being
announced, and some that were to just show they are out there, but with no
intention of actually being used.  Heck just the other day I was talking with
some about an ISP purchase, and that one of the sellers got the ISP to let him
keep one of the /18's personally.  I know the guy, he has no place to use it,
just knows that IP space costs $$, and as it was a pre-ARIN block from long
ago, knew he could just keep hang on to it in case he had a need for it
sometime.   So there is LOTS of wasted space, without a doubt, and at times a
legit person would really use a /24 and has a slim chance of getting it..

On a side note not list related, interesting ham call, had to look it up just
to see if it was actually real.. WB3FFV here by the way..  *smiles*
