Oh, and did you hear the US is finally switching to the metric system?


Say what? Why?

...IPV4 allows 4 bytes for the numeric IP address. IPV6 allows for 6 bytes. This means that IPV4has a hard limit of 4,294,967,296 unique addresses while IPV6 has an upper limit of 281,474,976,710,656 unique addresses.


IP4 does allow for only 4 address bytes, but IP6 uses 16bytes... that is 128 bits (vs. IP4's 32 bits). For a total address space of 340,282,366,920,938,463,463,374,607,431,768,211,456 addresses.

Of course just as IP4 could actually has less usable addresses than it could theoretically address (each byte, and sometimes even specific values within a byte had specific meanings) IP6 also imposes meaning upon the bytes - so there really are not 3.4028x1038 addresses available. But it IS a whole lot all the same.

But there is actually a lot more to IP6 than just addresses. It changes the underlying format for packets. It is not exactly in-expensive to retool everything for IP6 especially while still supporting older IP4 traffic.

Most consumer devices are IP6 compatible. but now the networks and software need to be as well.

What about the class D and E addresses?

And how much is gonna cost a valid IP address after the switch?

I think we need to take DIC underground. We must take all precautions to assure DIC's survival. So here are some options...

1) We construct a digital bunker which DIC will live in for the next 2 years complete with post rations, full supply of silly comments, data flow apparatus and emergency power backup. This would be the Noah's ark solution.

2) We can cryogenically freeze DIC and left in suspended animation until the year 2036 where it will be reanimated and with IPv7 addresses. This is the Demolition Man solution.

3) We develop a worm hole which we will push DIC through and into a parallel dimension where IPv4 still thrives alive and well. This is the Slider's solution.

4) Lastly, We make it slip and fall and hit its head on the bathroom toilet where it will come up with the flux compacitor which will make time travel possible. This is the back to the future solution.

So do I need to setup a poll for this or do you guys know what you want to do?


LMAO Demolition man solution. I am soooooo using that somewhere somehow on one of my social networks lol.

I don't get this either. Every network engineer I talk to acts like this is 150 years down the road or something or the concepts are 1 for 1 transferable.

I have looked at the IPv6 standards and they are radically different from IPv4.

Also, I have been thinking about picking up one of those free certs in IPv6 because I got a feeling that any knowledge of IPv6 will be worth gold shortly.

I am amazed that this is still an issue. You would have thought that we would have transitioned a little faster than this.

Back in 2000 I remember hearing that the transition was just around the corner and that I'd better get familiar with the new standard or I'd become a dinosaur. I was a Solaris admin at the time and Solaris 8 (latest) supported IPv6, so it seemed to me that it was upon us. Funny how things work out.
