1 00:00:04,750 --> 00:00:09,020 What am I going on now with how about the network address range. 2 00:00:09,020 --> 00:00:15,010 But then the way says he wants you to know it first OK it's. 3 00:00:16,390 --> 00:00:21,800 OK now and that it was the logical dress is up into two parts the network address and the host address. 4 00:00:21,860 --> 00:00:23,500 You already know that I told you this. 5 00:00:23,580 --> 00:00:29,710 I don't know whether it will give you a unique number because of some that it's not going to be zero 6 00:00:29,820 --> 00:00:35,260 at the end just because the zero at the end doesn't mean that it's a network idea. 7 00:00:35,500 --> 00:00:40,230 Guys let's call it it'll be a unique number based on the summary. 8 00:00:40,800 --> 00:00:44,790 Also address one that if you you know this you know there's you know there's you know this. 9 00:00:44,800 --> 00:00:45,570 OK. 10 00:00:46,000 --> 00:00:51,100 Well then if I knew who you are on that particular network again based on this I'm in math. 11 00:00:51,340 --> 00:01:05,050 So the powers that be have said then in a binary format and we look at it zero over 127 is the actual 12 00:01:05,230 --> 00:01:12,230 network address range 0 1 points up OK. 13 00:01:12,620 --> 00:01:20,940 So by their definition that's the range for a classy but it doesn't take into consideration they are 14 00:01:20,980 --> 00:01:25,480 reserved I putrescence Well ideogram for that. 15 00:01:25,500 --> 00:01:26,510 No. 16 00:01:26,610 --> 00:01:27,610 All right. 17 00:01:27,920 --> 00:01:30,410 So that's a class a range and biner. 18 00:01:30,470 --> 00:01:30,960 OK. 19 00:01:31,020 --> 00:01:33,570 Your other ultrasound is what causes confusion. 20 00:01:33,860 --> 00:01:36,950 There are about some books 0 0 0 0 0 127 21 00:01:40,310 --> 00:01:44,480 years ago my book on Amazon IP address. 22 00:01:47,410 --> 00:01:49,320 There it is right here. 23 00:01:49,550 --> 00:01:50,110 OK. 24 00:01:51,190 --> 00:01:54,020 The only IP work you will ever need. 25 00:01:54,220 --> 00:01:56,220 Look nothing at it with the girls. 26 00:01:56,350 --> 00:01:57,580 I cut through the red tape. 27 00:01:57,640 --> 00:01:58,560 OK. 28 00:01:59,120 --> 00:02:02,200 Anyway let's go to class B. 29 00:02:02,200 --> 00:02:04,750 Class B is wrong 20 21. 30 00:02:04,780 --> 00:02:05,350 That's cool. 31 00:02:05,350 --> 00:02:06,040 That's right. 32 00:02:06,040 --> 00:02:07,190 No big deal there. 33 00:02:07,210 --> 00:02:08,100 We're going to go there. 34 00:02:08,110 --> 00:02:09,060 I'm happy with that. 35 00:02:09,310 --> 00:02:09,780 All right. 36 00:02:10,000 --> 00:02:11,660 That's how it looks in binary. 37 00:02:11,890 --> 00:02:16,920 So if you're asked in a certification exam which are not. 38 00:02:17,490 --> 00:02:18,440 OK. 39 00:02:18,460 --> 00:02:19,340 They used to. 40 00:02:19,420 --> 00:02:20,650 Long time ago. 41 00:02:20,770 --> 00:02:29,370 Back in the days of Fred Flintstone ask you to stop in your college because the professors want to show 42 00:02:29,370 --> 00:02:30,870 their knowledge. 43 00:02:30,930 --> 00:02:32,010 They may ask you this. 44 00:02:32,280 --> 00:02:32,870 OK. 45 00:02:33,180 --> 00:02:35,800 But here are their definition. 46 00:02:35,910 --> 00:02:37,830 That is 121 anyone. 47 00:02:38,220 --> 00:02:40,380 But I'm going to do a couple of surprises. 48 00:02:40,590 --> 00:02:43,690 Get you so give you something actually. 49 00:02:44,560 --> 00:02:45,130 All right. 50 00:02:45,190 --> 00:02:46,590 And then we have the class the rage. 51 00:02:46,600 --> 00:02:48,160 Who is this group. 52 00:02:48,380 --> 00:03:03,400 Or I go from 1:28 or 1:29 glossary is really one of the two that should be two to 223 192 to 223 192 53 00:03:03,800 --> 00:03:05,160 to 223. 54 00:03:05,160 --> 00:03:07,090 What's that again that's the title. 55 00:03:07,110 --> 00:03:07,940 It's a typo. 56 00:03:07,980 --> 00:03:08,970 It's a typo. 57 00:03:08,970 --> 00:03:12,520 It's a typo 192 to 223. 58 00:03:12,640 --> 00:03:16,530 I tried there in the minor and you can see in the binary area you add those two bits up. 59 00:03:16,560 --> 00:03:20,310 That's one of the two you are these votes up is 223. 60 00:03:20,310 --> 00:03:21,680 So this is just a typo. 61 00:03:21,690 --> 00:03:22,650 Don't go crazy. 62 00:03:22,670 --> 00:03:25,860 Been going say all I got those letters are all I'm confused. 63 00:03:25,860 --> 00:03:27,090 No. 64 00:03:27,240 --> 00:03:28,380 Just out of the mine. 65 00:03:28,420 --> 00:03:28,970 OK. 66 00:03:28,980 --> 00:03:32,680 These two are tables forget about these because you can see the same number of those. 67 00:03:32,920 --> 00:03:35,570 OK is one or two 223. 68 00:03:35,730 --> 00:03:37,240 But I guess by their definition. 69 00:03:37,350 --> 00:03:39,880 Well look 192 but 223. 70 00:03:39,900 --> 00:03:40,580 How dare you. 71 00:03:40,600 --> 00:03:41,010 No. 72 00:03:41,160 --> 00:03:42,770 OK. 73 00:03:42,930 --> 00:03:43,900 That's the range. 74 00:03:43,920 --> 00:03:44,600 That's true. 75 00:03:44,790 --> 00:03:45,730 That's true. 76 00:03:46,410 --> 00:03:48,840 But again we're going to dive deeper. 77 00:03:48,890 --> 00:03:49,930 I know. 78 00:03:50,100 --> 00:03:53,850 One addresses the any the ranges from multicast purposes. 79 00:03:53,880 --> 00:03:56,000 They start from 224 to nine. 80 00:03:56,210 --> 00:03:58,420 Now everybody says multicast. 81 00:03:58,490 --> 00:03:58,920 Yes. 82 00:03:58,950 --> 00:04:03,620 Is a draft that you use right when configured on. 83 00:04:03,630 --> 00:04:04,320 And you know. 84 00:04:04,560 --> 00:04:09,740 So a group of individuals can join in in that particular multi-tasked. 85 00:04:09,840 --> 00:04:10,490 Right. 86 00:04:10,660 --> 00:04:17,220 Like every example and every book that's ever been written will tell you webinars like web access or 87 00:04:17,700 --> 00:04:24,080 join me don't me or whatever the case may be right but more important than that is. 88 00:04:24,120 --> 00:04:25,460 And we'll talk about later. 89 00:04:25,530 --> 00:04:34,480 One point that is your routers your rodders updates right even using the dynamic routing protocol. 90 00:04:34,650 --> 00:04:43,060 They send updates while they send updates in multicast broadcast Ripp version one does use broadcast. 91 00:04:43,070 --> 00:04:48,690 That's why I reversions you came around and it's now multicast all of them are running protocol even 92 00:04:48,690 --> 00:04:55,770 in 9:36 have multicast updates which use to object to a bigger neighbors. 93 00:04:56,560 --> 00:04:58,750 The range and I make fun of this. 94 00:04:59,060 --> 00:05:00,480 95 2:42 2:55 96 00:05:03,380 --> 00:05:10,210 listen in the book says it's for scientific purposes I call it Black Ops I call it all sorts of crazy 97 00:05:10,210 --> 00:05:11,490 stuff you know army. 98 00:05:11,620 --> 00:05:13,080 So you can use it. 99 00:05:13,090 --> 00:05:14,440 You don't use it. 100 00:05:14,440 --> 00:05:15,900 They may ask you about it. 101 00:05:16,060 --> 00:05:17,030 Don't worry about. 102 00:05:17,170 --> 00:05:19,170 OK. 103 00:05:19,300 --> 00:05:24,660 If they ask you about this or you think a network plus exam. 104 00:05:25,020 --> 00:05:29,490 But again you're in college or in school you know are in our 10th grade or something they may ask you 105 00:05:29,500 --> 00:05:30,420 something like this. 106 00:05:30,580 --> 00:05:31,700 OK. 107 00:05:32,110 --> 00:05:33,430 But it's very simple. 108 00:05:33,430 --> 00:05:38,600 So basically what they wanted you to know and this particular one they say no addresses. 109 00:05:38,800 --> 00:05:42,310 They wanted you to know the binary the binary the binary. 110 00:05:42,340 --> 00:05:43,900 OK that's it. 111 00:05:43,900 --> 00:05:45,470 That's all they needed you to know. 112 00:05:45,730 --> 00:05:47,850 Well I've been a little bit of the Union action.
