The next topic of discussion

00:06

is Internet Protocol version six or I. P v six.

00:11

Ah, lot of people are intimidated by PB six because it is written in hex a decimal.

00:16

If you remember, our hex numbers

00:20

29123456789 and then a through F, which is a B C D E f.

00:28

So instead of saying 10

00:31

the number 10 is represented by an A because it comes right after nine inaccessible, so in hacks. If I were to write them out, you go from one through nine and then, eh

00:45

for the number 10. Since it comes right after nine, the number 10 is represented by an A in hex, a decibel.

00:54

Now people are intimidated by PB six, I assure you, it is nothing to be afraid off except for the tedious typing required to type out of lengthy or address.

01:03

And we will simplify it.

01:04

And I B B six address is

01:07

128 bit address, written in eight fields of 16 bits, each separated by a colon.

01:14

What does that mean? Over Let's write down an I P V C six address.

01:22

Cole And let's make this easy on us by picking zero's a lot of zeroes.

01:29

0000 So eight fields of 16 bits

01:34

each. So I need eight of these fields, which are separated by a colon,

01:44

colon. 0000 colon 0000 So 123456

02:06

So this represents an I P. V six address, and it looks really long and it looks really complicated, but it's it's really not.

02:15

remember that each hex character

02:22

so each hex character represents reach. Hex number or letter represents four bits.

02:29

So if each fields have four has four of these characters, you get a total

02:43

If you add up 16 times eight you yet

02:53

now would you have to type or right in this hole

02:57

mess of numbers and letters every time.

03:00

There are rules to shortening

03:04

I P v six addresses rules for shortening i p v six addresses. The first rule is leading. Zeros may be omitted so you can leave out the leading zeros

03:24

ah, field 2nd 1 says successive. Feels off. All zeros may be represented

03:36

by a double colon, but only once leading zeros maybe omitted and successive fields of all zeros may be represented by a double colon.

03:49

But only once. Let's see what happens to this address I have written down. Once I applied these rules

03:54

becomes a lot easier.

03:57

I have 2002 then I have two successive fields of zeroes here.

04:04

into a double Colin? Just represent them by a double colon. Of course I can

04:13

So these two fields are taken. Care off now.

04:17

leading zeros maybe omitted. These 1st 3 zeros can be considered leading zeros,

04:24

so I can admit them.

04:27

And I can simply say

04:32

Now I have four zeros in a row.

04:35

I have three successive fields of zeros. Cannot turn these into a double colon.

04:41

Well, the rules, said successive feels off. All zeros may be represented by a double colon, but only once. And I've already used up a double colon, so I can't use the double Colin again.

04:54

is this a leading zero? Yes, it is for this one. This a leading zero? Yes, it is. For this zero is this is leading to know. Yes, it is for this zero. This last year was not a leading zero because it does not have a zero to the right off it.

05:06

So the 1st 3 zeros are leading zeros. So I can omit the 1st 3 and right zero on colon

05:14

again for the 1st 3 zeros because they're leading zero

05:18

again. Omit the 1st 3 zeros because they're leading again just to a zero last zero off each of these fields I wrote down here,

05:29

then zero want to be. I can write us one to be after admitting the leading zero.

05:36

I can also shorten this address as

05:45

This time I'm gonna use the double Colin hair instead of hair.

05:49

So I'm gonna just omit the 1st 3 leading zeros. Say colon zero.

05:55

Then again, omit the 1st 3 leading zero said colon

06:01

Then you admit the 1st 3 leading zero in front of the eh? So Sekula

06:10

then these three fields

06:18

And then the last field. I can see

06:21

one to be after meeting the first leading zero.

06:26

Now, both of these are valid shortenings for this I p v six address.

06:31

Both of these are valid shortenings for this I p v six address.

06:36

Now can I tell where how many fields of zeroes are gonna be

06:42

where these double Coghlan's recite? Well, I have a total of 123456 fields, which means

06:48

these two these this double colon represents two fields of zeros to give me a total of eight fields

06:56

or looking at the bottom 112345 I have five field, which means these two double Collins represent three additional fields of double off successive zeros.

07:11

are valid shortenings for this I p v six address. Now

07:15

we have seen how to short and I p v six addresses.

07:19

How about the I P V six sub net mask? Well, I p v six sub net mask works exactly like the I P Fi four sub net Master

07:29

But instead of written out in hacks, thank God it is on Lee represented

07:35

the slash format or the cider notation.

07:39

So let's say that this address has a slash 64 mask, which means the 1st 4 fields 16 plus 16 16 16 or 64 bits

07:53

If I were to write out the network address and the network and dress just the network address

07:59

in I. P. V six is called the prefix,

08:01

or the sub net Mask is called the Prefix, which equates to the network address because it tells you how many bits in the I P V six address belongs to the network.

08:11

And remember, it works exactly the same as an I. P V four sub net mask.

08:16

This network address would translate to

08:24

Now I can't use a Colin Colin here

08:26

because if you look at a night PV four address 1 51 01 45.10 And let's say this was a slash 24.

08:35

If I asked you for the network address, what did you do? 1 51 01 45.0 slash 24. You set all the network bits through zero

08:46

in the same way. If I'm going to set all the network bits to zero after a all these four field. 00000000000001 to be field are to be set to zero, then I cannot use the double Colin hair, for it has to be used

09:05

or my host portion off my TV six address.

09:11

Colin zero commit the 1st 3 zeros, the leading zeros again. Zero I omitted the 1st 3 leading zeros

09:22

and Colin A, then Coghlan Coghlan,

09:26

setting the host portion of the I. P. V six address to zero

09:35

Next, we're going to explore the I P V six

09:39

you I address format.
