1
00:00:00,230 --> 00:00:02,240
So, as I mentioned before.

2
00:00:03,030 --> 00:00:06,480
The IPv4 address is a 32 bit number.

3
00:00:07,300 --> 00:00:12,100
Which allows us to address maximum of two to the power of 32 devices.

4
00:00:12,250 --> 00:00:13,270
In theory.

5
00:00:14,380 --> 00:00:18,670
That means there are fewer than 4.3 billion addresses available.

6
00:00:18,700 --> 00:00:20,020
See where I'm going with this?

7
00:00:20,260 --> 00:00:28,210
It's a problem because there are many, many, many, many, many, many more than 4 billion Internet

8
00:00:28,210 --> 00:00:30,280
connected devices in the world.

9
00:00:30,460 --> 00:00:38,260
Desktop and laptop computers, smart phones, smart TVs, smart cars, even smart fridges, smart ovens.

10
00:00:38,260 --> 00:00:40,000
You know, the Internet of Things.

11
00:00:40,290 --> 00:00:42,250
It's the future, baby.

12
00:00:42,910 --> 00:00:47,230
This has led to a shortage of IPv4 addresses.

13
00:00:47,920 --> 00:00:52,660
So my friend and fellow genius, what is the solution to the problem?

14
00:00:53,920 --> 00:00:58,810
I think the long term solution is to switch to Internet protocol Version six.

15
00:00:58,840 --> 00:01:00,010
IPV six.

16
00:01:00,310 --> 00:01:05,290
IPV six has trillions of trillions of addresses.

17
00:01:05,470 --> 00:01:09,220
Enough to give every computer in the world a unique IP address.

18
00:01:09,970 --> 00:01:12,580
We'll get into that detail very soon.

19
00:01:13,860 --> 00:01:21,750
But the most important effort to migrate the IPv4 shortage is using network address translation Nat,

20
00:01:22,020 --> 00:01:29,280
which allows a private network to use one public IP address and that permits lots of private addresses

21
00:01:29,280 --> 00:01:30,840
in the private network.

22
00:01:30,860 --> 00:01:31,740
But wait a second.

23
00:01:31,770 --> 00:01:32,550
Wait, wait, wait.

24
00:01:32,700 --> 00:01:34,080
Private network.

25
00:01:34,080 --> 00:01:34,830
Nat?

26
00:01:34,860 --> 00:01:36,160
What the heck are you talking about?

27
00:01:36,180 --> 00:01:38,580
Now, I thought you wanted to go to IPv6.

28
00:01:39,530 --> 00:01:40,430
Let me explain.
