1 00:00:01,170 --> 00:00:04,860 OK, so let's start the interesting topic of. 2 00:00:05,620 --> 00:00:13,380 So even though I'm going to get into the finer point of being in Chapter six introduction to the Internet 3 00:00:13,380 --> 00:00:16,460 protocol, where are going to learn everything about the IP? 4 00:00:16,860 --> 00:00:21,430 I just want to give you some basic insight into this service server here. 5 00:00:22,080 --> 00:00:23,940 So let us get started. 6 00:00:24,600 --> 00:00:32,940 In a sense, DHC server that is dynamic host configuration protocol, as a name suggests, assigns IP 7 00:00:32,940 --> 00:00:34,080 addresses to hosts. 8 00:00:34,920 --> 00:00:42,510 Now, this protocol gives us a much easier way to administer, but automatically providing the IP information 9 00:00:43,350 --> 00:00:47,280 than the alternative and tedious method of static IP addressing. 10 00:00:48,390 --> 00:00:56,610 Now a DCP server is configured by the administrator with a pool of addresses which can get some addresses 11 00:00:56,760 --> 00:00:57,700 of the limits. 12 00:00:58,140 --> 00:01:02,770 Now these are called as IP addresses used by the DHC Peaceable. 13 00:01:04,730 --> 00:01:12,660 The server isn't on the same segment as the DHP client, and this is one of the main hit of the Tsipi 14 00:01:12,680 --> 00:01:13,220 server. 15 00:01:14,000 --> 00:01:21,330 The broadcast won't be received by the server because by default, routers will not forward broadcast. 16 00:01:21,740 --> 00:01:26,150 Now, this property of router, I have already told you in the previous lecture's. 17 00:01:28,280 --> 00:01:35,000 Now, there's a figure on the screen I want you to pay complete attention to that figure now in the 18 00:01:35,000 --> 00:01:42,830 figure, the router is configured with the IP address command on the interface e0 of the road. 19 00:01:43,040 --> 00:01:43,790 Let me show you. 20 00:01:47,750 --> 00:01:56,450 E here is router, it is configured with actress e0 on its interface, the router E will forward that 21 00:01:56,450 --> 00:02:01,040 request as a unicast meaning instead of a broadcast. 22 00:02:01,040 --> 00:02:06,050 The packet now has a destination IP address of the DHC server. 23 00:02:06,080 --> 00:02:09,200 See, this is the server. 24 00:02:10,200 --> 00:02:17,970 So as shown in the figure, you can configure Routley to forward these requests and even use multiple 25 00:02:17,970 --> 00:02:20,610 Eliot Spitzer was for redundancy if needed. 26 00:02:21,000 --> 00:02:24,300 You can see here are the multiple Eliot Spitzer was. 27 00:02:25,620 --> 00:02:32,610 This works because the router has been configured to forward the request to a single server using a 28 00:02:32,610 --> 00:02:38,780 unicast or by sending the request to multiple servers via a director broadcast. 29 00:02:39,150 --> 00:02:41,920 So you can see the router is. 30 00:02:41,940 --> 00:02:45,330 This is going to forward a single request here. 31 00:02:48,300 --> 00:02:55,980 Now, personally, most of the time, I use a Windows Server to act as a server for my entire Internet 32 00:02:55,980 --> 00:02:59,620 work and have my routers forward the client requests. 33 00:03:00,360 --> 00:03:06,630 Now it is possible to have a DCP server on every network segment, but that is not necessary because 34 00:03:06,630 --> 00:03:08,510 of the routers forwarding ability. 35 00:03:09,270 --> 00:03:15,300 Now, in the next lecture, I'm going to tell you about the DCP operations in which you're going to 36 00:03:15,300 --> 00:03:21,300 learn if when a device or Windhorst approaches the DCP server for IP address. 37 00:03:21,510 --> 00:03:25,900 How is that process exactly takes place in the real Internet network? 38 00:03:26,310 --> 00:03:30,180 So in the next lecture, let us see the DCP operations.
