WEBVTT 00:07.160 --> 00:14.420 I wanted to take some time to explore who is now who is is a query and response protocol that allows 00:14.420 --> 00:21.680 us to identify registered users for domains and specific information associated with the internet. 00:21.680 --> 00:24.980 So there's two different functionalities that we can utilize. 00:24.980 --> 00:26.690 The who is feature. 00:26.690 --> 00:31.850 One is a website that is literally who is now other domains. 00:31.880 --> 00:34.490 Other uh, databases have that. 00:34.490 --> 00:36.320 For instance, I know GoDaddy has one. 00:36.320 --> 00:37.880 I'm sure Google has one. 00:37.970 --> 00:39.080 I prefer this one. 00:39.080 --> 00:41.510 It's literally called whois. 00:41.630 --> 00:45.020 And I can go in and I can put IP addresses or domain. 00:45.050 --> 00:51.530 Now I'm going to put in Amazon.com, hit enter and you can see that it provides me some good information. 00:51.530 --> 00:56.420 For instance, it tells me that Markmonitor incorporated is associated with it. 00:56.450 --> 01:02.420 It tells me who is Markmonitor dot com provides in the server. 01:02.840 --> 01:04.910 It tells us the referrer is markmonitor. 01:04.910 --> 01:07.460 Com it also provides us the status. 01:07.490 --> 01:11.570 It tells us when the information or the domain expires. 01:11.570 --> 01:16.370 For instance, this one expires on October 30th of 2024. 01:16.380 --> 01:19.620 It also provides us the date it was registered on. 01:19.620 --> 01:25.050 So for instance, Amazon.com came into being on November 1st of 1994. 01:25.080 --> 01:27.180 It's really not that old of a company. 01:27.210 --> 01:32.820 It was last updated on five over 16 of 2023, which means that it's lasting a little bit. 01:32.850 --> 01:39.690 We can also see the specific name servers associated with Amazon.com, as well as similar domains associated 01:39.690 --> 01:41.100 with Amazon.com. 01:41.130 --> 01:46.590 If we scroll down, we can see some registered contact information, and we can see that if we wanted 01:46.590 --> 01:52.920 to contact the domain owner, we would contact Legal Services or the legal department and Amazon. 01:53.040 --> 01:55.980 The Amazon Technologies Incorporated, that gives us the address. 01:56.010 --> 02:00.780 It even gives us a phone number and a fax number if people still use those anymore. 02:00.810 --> 02:04.770 Based on that, we know that it's in Washington with that 206 area code. 02:04.800 --> 02:10.110 We can find the administrative contact information as well as the technical contact information, all 02:10.140 --> 02:12.630 related back to the same department. 02:12.660 --> 02:18.930 Now, a lot of times this information will be well, I wouldn't say missing, but it's not there. 02:18.960 --> 02:21.480 A lot of times we're not pointing to a specific individual. 02:21.480 --> 02:22.980 We're pointing to a department. 02:22.980 --> 02:24.570 And this is on purpose. 02:24.570 --> 02:26.640 But there's some good information. 02:26.640 --> 02:30.930 If I wanted to identify the specific domain information associated with it. 02:30.960 --> 02:34.740 The next way to do it is by opening up terminal. 02:34.740 --> 02:36.990 And let me blow this up a little bit so you can see it better. 02:36.990 --> 02:41.580 And we literally type in who is Amazon.com now. 02:41.580 --> 02:47.070 It gives us the same information, but if we scroll up a little bit, it gives us an A guy or I should 02:47.070 --> 02:50.100 say a command line interface, uh, portion. 02:50.100 --> 02:54.330 And if I scroll up all the way to the top, a lot of the same information is still there. 02:54.330 --> 02:56.100 It's just not as easy to read. 02:56.100 --> 03:00.540 We can see that the updated contact information, we can see the creation date. 03:00.540 --> 03:03.120 And again, none of this information is changing. 03:03.120 --> 03:04.890 It's just in a different format. 03:04.890 --> 03:10.890 I'm often asked by brand new students whether or not one is more valid than the other. 03:10.890 --> 03:13.530 And to that I say normally it doesn't matter. 03:13.530 --> 03:19.020 The information is pulling from the same databases, and so it really is just how you perceive or how 03:19.020 --> 03:20.400 you want the data fed to you. 03:20.430 --> 03:25.650 Do you want it in a command line interface module or do you want it in a web documented module? 03:25.650 --> 03:28.350 It really depends on what you're trying to accomplish. 03:28.350 --> 03:34.350 I honestly feel like the CLI provides it in a better recourse because I can just scroll through it, 03:34.350 --> 03:37.050 but a lot of people like the web based a little bit more. 03:37.050 --> 03:41.970 And again, it provides us the same exact information, just in a different format. 03:41.970 --> 03:43.080 So here we go. 03:43.080 --> 03:43.980 That's who is. 03:43.980 --> 03:45.120 I hope this was helpful. 03:45.120 --> 03:47.280 Until next time we will see you around.
