WEBVTT 0:00:02.840000 --> 0:00:08.820000 Hello and welcome to this video titled Identifying Your Own IP Information. 0:00:08.820000 --> 0:00:13.440000 In this video I'm going to be showing you how to view your own IP address, 0:00:13.440000 --> 0:00:18.820000 subnet mask, and what default gateway your device has been using. 0:00:18.820000 --> 0:00:21.220000 I'm going to show you how to do it based on whether you're using Windows 0:00:21.220000 --> 0:00:25.400000 operating system, Linux operating system, or the Mac operating system. 0:00:25.400000 --> 0:00:28.480000 So that is my goal with this video. 0:00:28.480000 --> 0:00:34.160000 Let's start with viewing IP information in Windows. 0:00:34.160000 --> 0:00:36.960000 So first of all here I'm just going to show you, I'm going to show you, 0:00:36.960000 --> 0:00:39.880000 I'm going to give you the steps textually and then I'm going to do a demonstration 0:00:39.880000 --> 0:00:44.420000 of it. So there's always multiple ways to accomplish this. 0:00:44.420000 --> 0:00:49.740000 One way is to open the DOS window in Windows, enter a particular command 0:00:49.740000 --> 0:00:52.000000 called IP config. 0:00:52.000000 --> 0:00:55.760000 Let's take a look and see what that does. 0:00:55.760000 --> 0:00:59.900000 So here I have a Windows 10 device. 0:00:59.900000 --> 0:01:06.580000 So Windows 10, you can just click on the little Windows icon right there 0:01:06.580000 --> 0:01:12.700000 and then you can just type in command and then I'll get you to your command 0:01:12.700000 --> 0:01:20.320000 prompt. And then from there you just type one word altogether, no spaces 0:01:20.320000 --> 0:01:26.640000 IP config. You can see that right there. 0:01:26.640000 --> 0:01:31.580000 And then when you hit the enter key on your keyboard you will see your 0:01:31.580000 --> 0:01:41.740000 IP information. So we can see here that this is the IP address of my adapter. 0:01:41.740000 --> 0:01:46.360000 We can see the subnet mask that my adapter was given and we can see the 0:01:46.360000 --> 0:01:49.320000 router, otherwise known as the default gateway that I'm going to send 0:01:49.320000 --> 0:01:54.080000 my packets to if they ever have to go to destinations that are not on 0:01:54.080000 --> 0:01:58.340000 my network. So that's one way. 0:01:58.340000 --> 0:02:04.440000 Probably the best way because also with this exact same command if you 0:02:04.440000 --> 0:02:11.640000 want to dig into it a little bit more, you can also type IP config, a 0:02:11.640000 --> 0:02:14.780000 forward slash and the word all. 0:02:14.780000 --> 0:02:17.240000 And now you get all kinds of nitty gritty information. 0:02:17.240000 --> 0:02:19.980000 We're not going to go over all the details of this but not only do you 0:02:19.980000 --> 0:02:25.160000 see your IP address, your mask and your default gateway, you can also 0:02:25.160000 --> 0:02:29.020000 see other things like the IP address of the server that gave you your 0:02:29.020000 --> 0:02:34.120000 IP address. You can see the DNS server you're pointing to that's going 0:02:34.120000 --> 0:02:38.920000 to resolve your websites into IP addresses and a whole host of other things. 0:02:38.920000 --> 0:02:48.440000 So once again that command to get there was IP config forward slash all. 0:02:48.440000 --> 0:02:53.660000 But just for basic IP information just IP config by itself. 0:02:53.660000 --> 0:02:57.920000 Or if you're a fan of using the GUI, you don't have to use the DOS prompt 0:02:57.920000 --> 0:03:01.380000 at all. And that's gets us to this other thing. 0:03:01.380000 --> 0:03:07.460000 We could go into our settings, open up network and internet, select our 0:03:07.460000 --> 0:03:11.540000 network adapter in my case it's going to be ethernet, go to the network 0:03:11.540000 --> 0:03:16.700000 and sharing center and then click on ethernet followed by details. 0:03:16.700000 --> 0:03:19.120000 Now I know there's a lot of steps right there let's just go ahead and 0:03:19.120000 --> 0:03:21.180000 go right through it. 0:03:21.180000 --> 0:03:26.380000 So here in Windows 10 I click on the Windows icon, there's settings right 0:03:26.380000 --> 0:03:30.040000 there towards the bottom left corner I'm going to click on that. 0:03:30.040000 --> 0:03:34.700000 Now I'm going to click here for network and internet. 0:03:34.700000 --> 0:03:40.520000 Now in my case I'm using my ethernet so I'm going to click on that. 0:03:40.520000 --> 0:03:48.840000 Now from here I'm going to click on network and sharing center. 0:03:48.840000 --> 0:03:54.920000 And then if you notice right here by where it says connections, ethernet 0:03:54.920000 --> 0:03:57.460000 you can click on that. 0:03:57.460000 --> 0:04:07.580000 It says I have IPV4 connectivity see if I didn't it would be like IPV6. 0:04:07.580000 --> 0:04:10.420000 See how IPV6 says no network access. 0:04:10.420000 --> 0:04:14.500000 If I didn't have an IP address I'd see the exact same thing under IPV4 0:04:14.500000 --> 0:04:19.220000 connectivity. And now to actually see it I can just click on details. 0:04:19.220000 --> 0:04:22.800000 And there we see the exact same stuff we saw with the IP config command 0:04:22.800000 --> 0:04:28.500000 in DOS. We see my IP address, we see my subnet mask, my default gateway 0:04:28.500000 --> 0:04:31.000000 and a variety of other things. 0:04:31.000000 --> 0:04:35.720000 So those are two basic ways that you can obtain your IP information in 0:04:35.720000 --> 0:04:37.700000 a Microsoft Windows environment. 0:04:37.700000 --> 0:04:47.660000 Now if you're using Windows 7 or something else the steps are very similar. 0:04:47.660000 --> 0:04:51.760000 Now what if you're using a Mac like I am right now? 0:04:51.760000 --> 0:04:52.700000 How do you see it there? 0:04:52.700000 --> 0:04:55.040000 Well there's once again several ways we can do it. 0:04:55.040000 --> 0:04:59.280000 I'm going to show you the graphical way using the GUI in a Mac to view 0:04:59.280000 --> 0:05:00.740000 your information. 0:05:00.740000 --> 0:05:06.400000 So you're going to go to your system preferences, you're going to select 0:05:06.400000 --> 0:05:11.460000 your network icon and then right there your IP address and subnet mask 0:05:11.460000 --> 0:05:14.200000 are going to be displayed. 0:05:14.200000 --> 0:05:16.040000 So let's go to that. 0:05:16.040000 --> 0:05:20.740000 We don't need him anymore. 0:05:20.740000 --> 0:05:25.340000 Okay so we're going to go to system preferences, the thing that looks 0:05:25.340000 --> 0:05:28.440000 like a flywheel or a gear wheel there. 0:05:28.440000 --> 0:05:39.240000 We're going to go to network. 0:05:39.240000 --> 0:05:42.260000 And actually there's one step that I skipped. 0:05:42.260000 --> 0:05:43.680000 So right here yeah where is it? 0:05:43.680000 --> 0:05:45.020000 Where is the address? 0:05:45.020000 --> 0:05:45.960000 And you can't see it. 0:05:45.960000 --> 0:05:57.560000 So now we have to actually click on advanced and TCP IP and there it is. 0:05:57.560000 --> 0:05:59.040000 That's what we're looking for. 0:05:59.040000 --> 0:06:03.840000 So this gives us our IP address, subnet mask, and even our default gateway 0:06:03.840000 --> 0:06:06.980000 that we're using. 0:06:06.980000 --> 0:06:12.240000 So using the graphical approach on a Mac you'd start with system preferences 0:06:12.240000 --> 0:06:14.760000 and work your way down from there. 0:06:14.760000 --> 0:06:24.820000 All right what if we were on something that was running Linux? 0:06:24.820000 --> 0:06:26.920000 How do we get the exact same information? 0:06:26.920000 --> 0:06:30.160000 Well, unless we're going to open up the terminal or maybe you're already 0:06:30.160000 --> 0:06:31.900000 in the command line. 0:06:31.900000 --> 0:06:37.020000 And from there we're going to type a simple command, IFconfig and with 0:06:37.020000 --> 0:06:41.660000 IFconfig we'll see our IP address and subnet mask. 0:06:41.660000 --> 0:06:45.940000 So let's take a look and see what that looks like. 0:06:45.940000 --> 0:06:54.440000 So here is my terminal. 0:06:54.440000 --> 0:06:57.300000 I'll zoom in a little bit more so you can see that. 0:06:57.300000 --> 0:07:04.520000 IFconfig. And you might have multiple adapters so you might have to scroll 0:07:04.520000 --> 0:07:07.680000 through this to find the adapter that you're actually using. 0:07:07.680000 --> 0:07:10.460000 Many times it's going to be EN0. 0:07:10.460000 --> 0:07:14.480000 That's probably the first one you should look for and they'll say INET. 0:07:14.480000 --> 0:07:19.600000 Notice there's INET6 that's for IP version 6 and there's this INET which 0:07:19.600000 --> 0:07:23.160000 is INET which is short for IP version 4. 0:07:23.160000 --> 0:07:28.920000 And here you can see what my IP version 4 address is and what my mask 0:07:28.920000 --> 0:07:34.540000 is. Now unfortunately in Linux here the net mask is displayed as a hexadecimal 0:07:34.540000 --> 0:07:38.420000 number. In this video I'm not going to go over hexadecimal. 0:07:38.420000 --> 0:07:41.540000 If you're not familiar with hexadecimal I would recommend searching on 0:07:41.540000 --> 0:07:45.940000 INE. We do have other videos that go into the details of how to count 0:07:45.940000 --> 0:07:50.360000 and convert from hexadecimal into decimal but you just you do want to 0:07:50.360000 --> 0:07:51.960000 know that it is there. 0:07:51.960000 --> 0:07:57.540000 Now how do I find out what my default gateway is? 0:07:57.540000 --> 0:07:59.520000 Because in this particular case I'm not seeing that. 0:07:59.520000 --> 0:08:04.320000 I see my IP address, my mask and that is it. 0:08:04.320000 --> 0:08:08.380000 So to get your default gateway there's another command we can use. 0:08:08.380000 --> 0:08:11.340000 Of course there's multiple ways you can do it. 0:08:11.340000 --> 0:08:17.520000 The command one way is the net stat minus Rn. 0:08:17.520000 --> 0:08:19.860000 Let me zoom in on that. 0:08:19.860000 --> 0:08:21.840000 Net stat minus Rn. 0:08:21.840000 --> 0:08:24.180000 This is going to show you your routing table. 0:08:24.180000 --> 0:08:27.520000 Your IP before and IPV6 routing table. 0:08:27.520000 --> 0:08:30.120000 And if we scroll up towards the beginning of this output we don't really 0:08:30.120000 --> 0:08:32.360000 care about IPV6 right now. 0:08:32.360000 --> 0:08:37.840000 Net stat minus Rn right here. 0:08:37.840000 --> 0:08:41.220000 Default. And here's my gateway. 0:08:41.220000 --> 0:08:45.020000 So that is the IP address of my router that's in my network that I used 0:08:45.020000 --> 0:08:49.000000 to send packets to remote destinations. 0:08:49.000000 --> 0:08:54.480000 And just one more way just to give you another alternative in Linux that 0:08:54.480000 --> 0:08:59.780000 you can see. As you can do the command IP config. 0:08:59.780000 --> 0:09:11.020000 Hey wait a second Keith wasn't in your interface. 0:09:11.020000 --> 0:09:13.660000 Oops. All right. 0:09:13.660000 --> 0:09:15.840000 Zoom in on that. 0:09:15.840000 --> 0:09:21.040000 So IP config get packet and then whatever the interface was so if we scroll 0:09:21.040000 --> 0:09:24.220000 up here if I still have it. 0:09:24.220000 --> 0:09:28.640000 Yeah Cen zero right there. 0:09:28.640000 --> 0:09:34.840000 How I discovered so when I did when I did the IF config command and I 0:09:34.840000 --> 0:09:41.160000 just looked through that I found that E n zero had my IPV4 information. 0:09:41.160000 --> 0:09:44.520000 So now in this command down here if I type in E n zero. 0:09:44.520000 --> 0:09:47.300000 Now I get a lot of good stuff. 0:09:47.300000 --> 0:09:56.060000 IP config get packet E n zero and I can see here's my IP address. 0:09:56.060000 --> 0:10:01.400000 Here's the server that gave me that IP address. 0:10:01.400000 --> 0:10:04.280000 Here's my subnet mask. 0:10:04.280000 --> 0:10:06.840000 Ah now I don't have to worry about viewing it in hexadecimal. 0:10:06.840000 --> 0:10:10.060000 It actually displays as dotted decimal which is a lot easier. 0:10:10.060000 --> 0:10:12.800000 Here's my default gateway. 0:10:12.800000 --> 0:10:22.040000 So that was IP config get packet and then the name of your interface. 0:10:22.040000 --> 0:10:27.200000 All right so that my friends concludes this video on how to get your IP 0:10:27.200000 --> 0:10:30.720000 address using various different operating systems. 0:10:30.720000 --> 0:10:31.440000 Thank you for watching.
