1 00:00:04,480 --> 00:00:08,450 Log on to our favorite word. 2 00:00:08,880 --> 00:00:13,950 I want a goal calling hierarchical dressing. 3 00:00:15,360 --> 00:00:16,720 Why do we need it. 4 00:00:16,760 --> 00:00:25,740 Mamon scaleable just to have MAC addresses or something flat to every node out there in the world doesn't 5 00:00:25,830 --> 00:00:27,140 it can't be that way. 6 00:00:27,230 --> 00:00:29,740 It has to be structured like a pyramid. 7 00:00:30,120 --> 00:00:30,700 You can. 8 00:00:30,720 --> 00:00:33,520 You have to have some sort of skill ability. 9 00:00:33,600 --> 00:00:43,990 And that's what dressing the 32 bit address a structured as opposed to fly addressing which is not structure. 10 00:00:44,170 --> 00:00:50,920 They are the type of them Khawar by the structure approach was chosen for this capability for large 11 00:00:50,980 --> 00:00:53,140 enterprise networks. 12 00:00:53,240 --> 00:00:55,070 You can get away with it a small network. 13 00:00:55,070 --> 00:01:06,750 A lot of drastic I don't know 20 if you're not lazy 30 50 but when you start getting into the hundreds 14 00:01:07,320 --> 00:01:10,380 and definitely down dozens or hundreds of thousands. 15 00:01:10,440 --> 00:01:10,960 Yeah. 16 00:01:10,960 --> 00:01:20,430 No I know there are many ways to do take and I did it used to be called that decimal addressing that 17 00:01:20,600 --> 00:01:24,310 is called borrowed decimal whatever. 18 00:01:24,640 --> 00:01:25,710 DTN OK. 19 00:01:25,780 --> 00:01:26,450 But it doesn't. 20 00:01:26,530 --> 00:01:31,650 And you saw that when I say 1.0 there's also here's the binary form. 21 00:01:31,660 --> 00:01:32,960 Here are your offsets. 22 00:01:33,250 --> 00:01:35,870 The first two options are on 128 64. 23 00:01:35,920 --> 00:01:40,370 You add those two that makes 192 and the. 24 00:01:40,630 --> 00:01:43,060 That's the fourth force on it. 25 00:01:43,270 --> 00:01:52,250 And the second not that the on the first and third bit first third and fourth and fifth on. 26 00:01:52,450 --> 00:01:59,890 So that makes up 168 a 128 is on 32 is on the ball. 27 00:02:00,810 --> 00:02:02,150 An 8 is on. 28 00:02:02,160 --> 00:02:05,580 Now I will make 160 and then one is. 29 00:02:05,640 --> 00:02:09,300 This one this lonely one over here which is 1 and then 0 0. 30 00:02:09,580 --> 00:02:10,140 OK. 31 00:02:10,270 --> 00:02:14,080 And then obviously the hexadecimal number version to that. 32 00:02:14,170 --> 00:02:15,060 OK. 33 00:02:15,520 --> 00:02:16,660 Where. 34 00:02:17,050 --> 00:02:17,590 Oh my god. 35 00:02:17,590 --> 00:02:19,020 Back. 36 00:02:19,160 --> 00:02:22,140 I don't know how many years ago they give you stuff like this. 37 00:02:22,160 --> 00:02:29,090 You can convert a address to binary binary to an IP address or whatever. 38 00:02:29,180 --> 00:02:30,830 They don't do that anymore. 39 00:02:30,940 --> 00:02:33,230 You may see some IP addresses. 40 00:02:33,230 --> 00:02:34,580 So I have a calculator with you. 41 00:02:34,730 --> 00:02:38,110 Or go look at my conversion course. 42 00:02:38,180 --> 00:02:46,100 It's quick it's simple it's easy to do and you can convert any any hex number to binary to decile was 43 00:02:46,100 --> 00:02:48,560 binary as your middle raúl or whatever. 44 00:02:48,560 --> 00:02:55,640 Anyway I'll say here you will find that the IP address and hacks X-Pac for all except for IP. 45 00:02:55,700 --> 00:03:03,340 Obviously think takes a text and decimal 120 What address we have or the number. 46 00:03:03,370 --> 00:03:07,020 I got undecillion I forgot the actual name. 47 00:03:07,350 --> 00:03:11,030 And John undecillion out of addresses you know we're going to run out. 48 00:03:11,120 --> 00:03:11,990 OK. 49 00:03:12,290 --> 00:03:16,230 But you need to learn how to convert or get to my conversion course that I have. 50 00:03:16,400 --> 00:03:23,990 You can take a look at it very simple do I do it here or just courier Kiger where you go for it. 51 00:03:24,140 --> 00:03:24,650 OK. 52 00:03:24,830 --> 00:03:33,250 But the reason for hierarchical addressee is simply just that we need that 3 to be 32 bit address in 53 00:03:33,250 --> 00:03:40,940 a structure and more so I the six I of run out of IPV four because we were silly I think nobody is going 54 00:03:40,940 --> 00:03:42,010 to use the Internet. 55 00:03:42,410 --> 00:03:43,500 Yes they are. 56 00:03:43,550 --> 00:03:46,940 And when you started your IP addresses were like they were can they. 57 00:03:47,000 --> 00:03:48,830 Now we're worried about. 58 00:03:48,950 --> 00:03:52,930 Well now we got a few six which started 20 bits OK. 59 00:03:53,150 --> 00:03:56,060 Now we don't have an issue on this time. 60 00:03:56,120 --> 00:03:58,040 Undecillion addresses either. 61 00:03:58,130 --> 00:04:07,650 I remember her network is 15 quintillion addresses you can have within that network me on camera. 62 00:04:07,940 --> 00:04:15,310 And then we have ICMP BERLIJN states that had to begin to address really you duplicate address thing 63 00:04:15,440 --> 00:04:16,500 clean addresses. 64 00:04:16,810 --> 00:04:18,430 OK. 65 00:04:18,710 --> 00:04:26,290 Either way no that this is why and now we have sex is even more structured more structured the way you're 66 00:04:26,300 --> 00:04:32,230 routing tables will have to suffer us much when you have things in a structured manner. 67 00:04:32,330 --> 00:04:34,690 They can find things a lot easier. 68 00:04:34,730 --> 00:04:39,180 They don't have to look through a billion addresses to find where your.
