00:00:07,350 --> 00:00:09,030
- Welcome to lesson 12.

2
00:00:09,030 --> 00:00:11,460
In this lesson, you'll
learn about networking.

3
00:00:11,460 --> 00:00:14,670
I'll start by explaining network
basics, just to make sure

4
00:00:14,670 --> 00:00:18,160
that you know about IP
addresses, including IPv4

5
00:00:18,160 --> 00:00:22,380
as well as IPv6, routers and DNS servers.

6
00:00:22,380 --> 00:00:24,510
Next, we'll discuss
managing and troubleshooting

7
00:00:24,510 --> 00:00:27,810
of run-time network configuration,
which allows you to learn

8
00:00:27,810 --> 00:00:29,280
about the tools that are required

9
00:00:29,280 --> 00:00:32,790
for troubleshooting networking
in case anything goes wrong.

10
00:00:32,790 --> 00:00:35,190
I'll explain what is behind
network device names,

11
00:00:35,190 --> 00:00:38,250
like eth0 and ens33.

12
00:00:38,250 --> 00:00:40,050
You'll learn how to manage hostname

13
00:00:40,050 --> 00:00:41,580
and hostname resolution

14
00:00:41,580 --> 00:00:42,750
and at the end of this lesson,

15
00:00:42,750 --> 00:00:45,960
I'll show you how to manage
persistent networking.

16
00:00:45,960 --> 00:00:47,220
The lesson ends with the list

17
00:00:47,220 --> 00:00:48,810
of commands that were covered

18
00:00:48,810 --> 00:00:50,823
as well as a lab and lab solution.
