Hello and welcome back to I see anyone interconnecting Cisco networking devices are one
this upset 712 i p v six basics on trend Darren of your structure For this course
you lost video win or the lessons 7.1 all review. And in this episode of recovered the epi six basics ah, little bit how it's the similarities and differences between the version four
we're gonna get into shortening and lengthening the I P version six addresses with the rules you can use. And lastly, we will look at how to get the prefix orthe e subject i d of I p version six address.
And like I said, we're gonna look at I p version six basics, meaning we're gonna look at the different rules. We're gonna look at the similarities, were gonna look at how you can shorten the rule or how you can lengthen it back out. And lastly, we'll look at finding these sub that I d
so quick Pre assessment. Hopefully, guys, remember this from the binary lessons. How many bits are in a bite? I'll give you a few seconds.
All right. Hopefully you got 88 bits are in eight bites. You'll see why that math is relevant here. In a second.
Version six is an R F C. 24 60. You see the HPV six header off to the right. As you can see, the source i p address and destination I P address are both 128 bits.
Um, so the new I P version also meant we had to have the new I Pierre new protocols and I'll show you some of the routing protocols and next slide here. But we have a new version of Ping or ICMP version six. And instead of our the address resolution protocol, we now have the neighbor Discovery protocol are NDP,
and we have always be virgins. Three straight there already because next slide.
So I'd be version six. Address what it is. It's 128 bits, like I said or 16 bites cause 100 28 by 6 16 and this one we actually deal with Hexi Decimal and said a decimal or decimal you had zero through nine
is your options. Hexi Decimal. You have zero through F or you have a total of 16 characters to choose from.
If you look off to right there is the hex to binary two decimal chart. So you you can see you know, half equals 15 things like that. So keep that chart handy. It's kind of useful that when you're first starting out to understand,
so the 128 bit addresses a total of 32 hex digits because 32 are one hex digit equal four bits, As you can see in the binary There, there's a total of four binary bits in one hex digit.
The writing is actually worked. The same is I paid for. You know, the host is gonna need an I p is going to need a default. Gateway to send its traffic to the router is gonna Dean capsule ate the happy version six. Pack it. It's gonna re encapsulate the packet and then it's gonna make routing decision off the routing table. It all works the same off that,
we're gonna go ahead. Look at the new routing protocol that we have So rip the newest version for diversion sixes and next generation.
And yes, it was after Star Trek to Next generation, which I think is awesome.
Oh, SPF version three as RFC 53 40. There's a few other ones that are related to it. Um, the newest version has some support for I p version for I p v four. Well, e I j r p version six.
Ah, Cisco member 60 owns it. But as releases, an information RFC saw this can use it.
then we have multi protocol B g p four who won't get into that. And I see anyone just know it is a new routing protocol for I p version six.
So we get ready. How to write my PB six address? Just stick this bullet by bullet here.
So remember, we have eight blocks of four hex digits.
So remember, we have
the total addresses 128 bits or 32 hex character's or 16 bites. So if you look at the example there that is fully expanded Goebel I p. Address. There are people just six address,
so realize it's a lot to look at, but if you break it down piece by piece, it's not too bad. So you think off. Four. There's eight blocks of four hex digit, so if you count those out there should be four by eight.
and then you can if you want to. You can convert each
Hoechst character into binary still.
but as you can see in the binary format below, that's would be not the most efficient use of your time to do this. That's why we have cakes, characters and decimal and other bits.
so one way we can shorten these I peed years and six addresses because even writing out 32 heist characters is still cumbersome, we can shorten it down. They made some rules in the our seas to allow us to do this. So first thing we can do, we remove any leading zeros. So these would be the ones that would be like consecutive to the left of the Cohen,
we could take
this address out here and this address out here
so we could remove those zeros. Now, remember, it would be at the end, so we would have to keep these ones because it's to the left.
All right, we don't want to keep the ones officer right. It's just the way they were put in the rule. We never pull the zeros to remove the zeros that are to the right here on Lee. The ones that would be,
um, to the side of the corn.
So they are. One we can do here is we can remove consecutive blocks of zeros.
I'll show you what that means here. We'll get into the shortening exercise here in a second.
So means if let's say these are zeros and this is zero's
weaken shortness up by just doing to Collins.
Now, you can do this one time in an I p version six address. So if you have another block down here, that's all zeroes. You just replace this with the colon. Zero corn.
It would just be that because if you did want to come down here and two calls down here,
you wouldn't actually know
where like this one could be. The two zeros, two blocks of zeros. This one could be the two blocks of zeroes you wouldn't actually know. So they allow you to. Don't we do it one time in the address.
So we're gonna move into the I P V six shortening
address here. So I'm gonna go in and help you guys out with this 1st 1 here, so we have the full I P V six address here,
and I'm sure you what will be done?
So the first
thing here as we removed zero and about the zeros we'll just move down the line
and wrote removed leading zeros.
And we keep these ending ones like this one. We would keep this.
So if we look and we had 2500 and a B G, which is correct 23
this one would stay of things. There's no leading zeros. We removed leading zero here.
Yes, and stay the same.
And I want to go there.
And we removed 10 off of there.
So what I want you guys to do is do the same thing for this 1st 1 here
on and I will deposit video and shows that
All right, so hopefully you guys got this one.
So hopefully you got this because we keep Effie 00 the same. We remove the leading zeroes here.
This wood won't They should be an f. I apologize.
So keep that one
and ABC would be insane. 98. This would be the same.
And we remove these two leading zeros to lose two to Delta and were moved. These ones
leaders were just five.
So this next one here is going to include the
ah, the double colon, removing the the blocks of zeros.
This one will include
the same thing.
but it, you know, has that issue where you can't use both and it has to be two or more blocks of zeros,
and this one will include both concepts here. So if you want to go ahead and pause the video and we will walk through them here in a second,
All right? Hopefully, you are done here.
I'm gonna bring up this 1st 1 walk through that.
All right, so let's go through. We can replace both of these with the Collins.
What should be here,
And that is it.
So hopefully you got that one. Just replace that with a double Cohen there.
I'm gonna go ahead and move onto the next one.
So here we would just replace this with zero, because we don't have two or more blocks of zeros,
and we can replace all of these
with this double. Colin.
Um, remember, if it's just zeros, you cannot have a double colon twice and it has to be two or more
So this one, Even if these were all A's,
you still could not have a double colon right here,
because it's not two or more. All right, we're gonna go ahead and move on to the last one here. Hopefully, you figured this one ounce.
So if we go in here,
we see three blocks zeros. So I'm just gonna go ahead and replace this with
A B C D can't be the same. We removed the zero on a 236
A. We remove the zero on the A three. Bravo
965 f stays the same.
So hopefully you guys got this.
If you need more practice, there should be a question sheet that in the course guide here.
Otherwise, we're gonna move on to making a full address from a brief
