1
00:00:03,330 --> 00:00:06,510
In the case of IP version 6 this is a bit different.

2
00:00:08,440 --> 00:00:14,410
We have to realize the sixth version of IP protocol is being increasingly used especially in Asia where

3
00:00:14,410 --> 00:00:17,790
the IP version 6 protocol has already become a default one.

4
00:00:20,190 --> 00:00:22,650
Other versions have fallen out of use.

5
00:00:23,100 --> 00:00:28,140
In Europe the fourth version of the protocol is still largely in use.

6
00:00:28,170 --> 00:00:34,020
Nevertheless even their operating systems of hosts and networking devices have built an IP version 6

7
00:00:34,020 --> 00:00:35,730
support enabled by default.

8
00:00:38,200 --> 00:00:41,980
Also IP version 6 is the default version of this protocol.

9
00:00:43,490 --> 00:00:49,250
If two hosts can use IP version 6 to communicate they will opt for this version instead of the fourth

10
00:00:49,250 --> 00:00:49,890
one.

11
00:00:52,190 --> 00:00:58,790
Administrators who for the time being have decided to ignore IP version 6 protocol managed networks

12
00:00:58,790 --> 00:01:06,150
in which this version is used and works administrators didn't not seem to realize this and do not monitor

13
00:01:06,160 --> 00:01:09,350
the IP version 6 traffic.

14
00:01:09,380 --> 00:01:11,040
This is a serious problem.

15
00:01:12,650 --> 00:01:17,580
Now why do we even have the sixth version of the IP protocol.

16
00:01:17,610 --> 00:01:24,690
The primary reason is that we've run out of IP version 4 addresses in the United States where the Internet

17
00:01:24,690 --> 00:01:26,180
was developed.

18
00:01:26,400 --> 00:01:29,710
There is still a number of IP version 4 addresses available.

19
00:01:31,810 --> 00:01:37,120
Some universities have bought out whole classes of addresses in advance.

20
00:01:37,210 --> 00:01:43,330
They possess a bigger pool of addresses than countries such as China or India these countries started

21
00:01:43,330 --> 00:01:46,120
to run out of addresses some time ago already.

22
00:01:46,120 --> 00:01:56,020
And so the transition to IP version 6 how to solve the problem of IP version 4 address exhaustion you

23
00:01:56,030 --> 00:01:58,420
can increase the pool of available addresses.

24
00:02:01,200 --> 00:02:10,110
IP addresses were extended from 32 to 128 bits a 128 bit number is a large one.

25
00:02:10,120 --> 00:02:12,080
So it is saved in a different format.

26
00:02:14,740 --> 00:02:18,290
The format consists of four digit groups of hexadecimal numbers.

27
00:02:24,470 --> 00:02:31,710
IP version 6 introduced an important change related to sudden getting an IP version 6 addresses the

28
00:02:31,710 --> 00:02:36,000
network address always has a fixed link.

29
00:02:36,020 --> 00:02:41,810
This is a marked difference from that IP version 4 which utilizes either classes or a CD-R and doesn't

30
00:02:41,810 --> 00:02:47,310
allow you to distinguish between the network and the host address and IP version 6.

31
00:02:47,310 --> 00:02:54,610
The first 64 bits always correspond to the network address 48 bits describe the main network and the

32
00:02:54,610 --> 00:03:02,590
remaining bits correspond the subnets the less 64 bits of the IP version 6 addresses the host address

33
00:03:05,310 --> 00:03:09,240
the IP version 4 addresses are arranged hierarchically.

34
00:03:09,490 --> 00:03:11,950
You can easily group them together into sublets.
