Funny, I have been doing IPv6 for more than 5 years but have been doing it though tunnels. Done some IPv6 exploring s well. In fact if you have an Apple Airport Extreme, if the WAN side is hooked in with a real IP number and not a internal IP like 192.168.x.x, it will create an IPv6 tunnel !
That’s what I’ve been saying all along.
Thanks! I need to start looking into IPv6, which I’ve ignored at least since it was IP next gen, because it’s creeping into my workaday world.
I remember, back in the day, when this was just beginning to take shape. We all feared it, as we didn’t understand it and we liked IPV4. Since retirement from the IT world I assumed IPV6 would be the law of the land by now but apparently this hasn’t happened yet.
not yet. It looks like this is something will have to be forced on the IT world. IPv4 is just too easy, I guess.
Yep, once you get the idea of IPV4 it is easy, but they should just about be out of addresses by now:)
Algore actually invented this BEFORE he invented the internet. (He just has problems with prioritizing.)
OK, now that you're totally confused, I actually think it's kind of cool that you posted this. I'll guarantee you there aren't 7 people over at the DU funny farm that could even begin to understand this article.
LOL! I thought it kinda cool, and required reading for our resident techies here. :)
Make that 11 things.
First thing:
What the hell is IPv6 addressing?
I read that IANA has about 5% of all IPv4 address left to issue. My company is begining to roll out IPv6 in our core. It has taken me a while to wrap my head around 52-bit subnets ;-)
LOL! OK, I don't know how versed you are in internet addressing, so I'll start kinda at the very basics.
The URL you type into browsers is called a Uniform Resource Location. It's essentially the english form of internet addresses. The browser takes what you type in and converts it to an Internet address.
Internet addresses currently are expressed in IPv4. That is, 4 32-bit numbers, separated by periods. For example, 127.0.0.1 indicates your local machine. Google has an internet IPv4 address of 66.249.92.104
Each of those number is between 0 and 255 (that's 32 bits long). However, due to housekeeping chores, and various short-sighted assignments in the 80's, the actual number of addresses that are available, is quite a few less than you'd expect. 232 is approximate 4,294,967,296 addresses, but we only have access to a subset of that. With the expansion of the Internet, we are approaching the upper limit of the number of devices that can be connected.
IPv6 uses 128 bits, rather than 32. This vastly increases the number of available addresses, and ensure we will not run out of addresses on the Internet. 2128 is about 340,282,366,920,938,463,463,374,607,431,768,211,456
The format of IPv6, though is quite a bit different that IPv4. That's what this article is about.
So in terms that I can understand, it’s sorta like the Post Office coming up with ZIP Codes?
NAT helped push it off, but even that’s only delaying the inevitable.
That not quite exact. ZIP codes are the area of an address. IP is the exact address. So instead of 4 billion possible addresses, IPv6 allows for a heck of a lot more addresses to be available.
Thank you!
I wasn’t trying to be a wiseass. Computer stuff intrigues me.
Yours is a great explanation, and I appreciate it!
Best Wishes!
Pete
