Well, here it comes.  World IPv6 Day.  Initially, I thought major sites that   
   are participating were going to turn OFF IPv4 for their test, but reading up on   
   it today, I don't think so.  Maybe someone more in the know could chip in about   
   that?   
     Anyhow, I've posted several times on Facebook about this, doing my small part   
   to spread the word about IPv6.  For those who somehow have missed out on the   
   history behind it, and are completely clueless; well, first, crawl out from   
   under your rock, then head over to test-ipv6.com.  First it'll run some tests   
   for you, then you can start looking up all about it.  But the basic low-down   
   is, Vint Cerf, one of the pioneers, basically committed the original IP   
   protocol to use 32bits of address space.  Our basic 255.255.255.255 address.   
   Couple this with the way the addresses are handed out, and we come to today,   
   whereby the last of the address space is being assigned.  Asia has already run   
   out of their allotment, and the rest of the regions are quickly following,   
   either this year or next.   
     In the phaseout of IPv4 (version 4) to IPv6, the first step is to run what's   
   called a dual-stack system.  Now, I'm a bit confused on exactly what Teredo is,   
   but I can tell you that on XP at least, it enables IPv6 functionality.   
   test-ipv6.com seems happy with it, and as a humble user, that's good enough for   
   me.  I seem to be all set.   
     But what's this?  My DNS fails the test.  All the work I've done over the   
   past couple years to learn about and implement IPv6 on my home computer, and my   
   home network, may be for naught!  Well, there are other DNS providers out   
   there, and if it really does cause problems, we may be able to use those.   
   test-ipv6.com doesn't seem too worried about it -- it says that particular test   
   is "bonus credit".   
      
     That's it for this short post about World IPv6 Day.  I think it's pretty cool   
   we're inching that much closer to dumping IPv4.  I'm tired of dynamic   
   addressing and NAT addressing and all the other kludgy schemes.  IPv6 may have   
   its problems, but I think it solves more of them than it creates.
