 Hello and welcome to this course titled
 Understanding DHCP, DNS, and NTP

0:00:14.140000 --> 0:00:18.780000
 services. I am Keith Bogart and I will
 be your instructor for the duration

0:00:18.780000 --> 0:00:22.200000
 of this course. Should you have any
 questions once the course is over

0:00:22.200000 --> 0:00:25.800000
 I've provided my contact information
 here so please feel free to reach

0:00:25.800000 --> 0:00:28.940000
 out to me and I'll help you
 to the best of my ability.

0:00:28.940000 --> 0:00:33.040000
 So there are just a handful of prerequisites
 I would like you to have

0:00:33.040000 --> 0:00:36.860000
 going into this video course so that you'll
 get the most out of it possible.

0:00:36.860000 --> 0:00:38.960000
 And you can see here there's
 this really just two.

0:00:38.960000 --> 0:00:42.640000
 Number one I want to have you make sure
 you have a general understanding

0:00:42.640000 --> 0:00:44.620000
 of the Internet Protocol.

0:00:44.620000 --> 0:00:49.720000
 All these features and protocols we're
 going to talk today work with IP,

0:00:49.720000 --> 0:00:51.060000
 the Internet Protocol.

0:00:51.060000 --> 0:00:54.220000
 And if you don't know what the Internet
 Protocol is, if you don't know

0:00:54.220000 --> 0:00:58.980000
 what an IP address is, this stuff
 won't make a lot of sense to you.

0:00:58.980000 --> 0:01:03.040000
 So I'm hoping you have some general
 familiarity with IP and you sort of

0:01:03.040000 --> 0:01:08.980000
 can visualize what an IP address
 is and why we need IP addresses.

0:01:08.980000 --> 0:01:12.360000
 So if that describes you,
 you're good to go.

0:01:12.360000 --> 0:01:14.600000
 So what are the course objectives?


0:01:14.600000 --> 0:01:16.160000
 Well, there's three
 primary things.

0:01:16.160000 --> 0:01:21.760000
 Number one I want to introduce you to the
 dynamic host configuration protocol.

0:01:21.760000 --> 0:01:28.020000
 Chances are 99% that you're already
 using it and you don't even know it.

0:01:28.020000 --> 0:01:31.940000
 Pretty much every device you have that
 has IP, whether it be your smartphone,

0:01:31.940000 --> 0:01:35.840000
 when it's connected to a Wi-Fi network,
 your tablet was connected to a

0:01:35.840000 --> 0:01:40.380000
 Wi-Fi network, or your laptop per PC,
 whether it's connected to a Wi-Fi

0:01:40.380000 --> 0:01:47.600000
 or a wired network, is utilizing DHCP
 to obtain its IP information.

0:01:47.600000 --> 0:01:50.500000
 So you probably might not be aware of
 that, but we're going to talk about

0:01:50.500000 --> 0:01:54.320000
 DHCP and how exactly
 it does that job.

0:01:54.320000 --> 0:01:56.620000
 Then we're going to
 move on to DNS.

0:01:56.620000 --> 0:02:03.060000
 So having basic IP information is really
 not enough for you to do the

0:02:03.060000 --> 0:02:06.640000
 types of things you accomplish every
 day, which is stuff, for example,

0:02:06.640000 --> 0:02:07.720000
 browsing the web.

0:02:07.720000 --> 0:02:09.680000
 How many hours do you spend
 browsing the web?

0:02:09.680000 --> 0:02:14.580000
 Well, browsing websites like INE or
 Google or whatever it is wouldn't

0:02:14.580000 --> 0:02:19.620000
 work for you if somebody a long time
 ago had not invented the domain name

0:02:19.620000 --> 0:02:24.340000
 service. So we're going to talk about
 what DNS is and what benefits it

0:02:24.340000 --> 0:02:27.880000
 gives you. And then we're going to talk
 about something called the network

0:02:27.880000 --> 0:02:32.720000
 time protocol. Now, if you're just a
 home user of a network, you probably

0:02:32.720000 --> 0:02:34.140000
 don't use the network
 time protocol.

0:02:34.140000 --> 0:02:39.460000
 However, if you are or aspire to be
 a network administrator or a network

0:02:39.460000 --> 0:02:44.160000
 engineer, chances are at some point
 in time, you'll need to implement

0:02:44.160000 --> 0:02:45.400000
 the network time protocol.

0:02:45.400000 --> 0:02:49.460000
 So we'll talk about why that's important
 and what it can do for you.

0:02:49.460000 --> 0:02:53.220000
 So with that being said, let's just go
 ahead and jump right into understanding

0:02:53.220000 --> 0:02:55.960000
 DHCP, DNS, and NTP.
