Now, let's get into the network side of Lennix.
Of course, this is not a network where you're going to be learning switches and routers.
That's completely a dedicated network job that you should look into.
But in Linux, even if you are system administrator or engineer, you have to know a few things of network.
What it means is when you are building or installing a Linux machine, you need to configure an IP address.
You need to know certain things, certain components of network to get it working and get it online.
What are those things?
Of course, the first thing is IP.
IP stands for Internet protocol.
IP address is could be like, for example, one a two one 68, one, two, three, four or whatever.
So depending on the organization you are in, you're probably going to have a different range of IP
addresses.
So your job is to assign an IP address and you should know what IP address is and what it looks like.
Subnet mask is an associated way to attach it to the IP address.
And then we have a gateway, Gateway tells the your computer which route you have to pick to send your
traffic out and to receive your traffic in.
So if you are in your home environment, your modem, the IP address of your modem will be your gateway.
Then we have the static and horses and DCPI was static, as if you are given an IP address from your
company, from your corporate environment, and you have to assign a dedicated IP to your machine that
is called static.
And when you reboot your machine, that IP does not change, whereas if it is set up as DCPI, the IP
address will change.
It will pick an IP from a pool of IP addresses.
And every time your system is rebooted, most likely it will change its IP address.
So in most of the corporate environment, you will be setting up a static IP address.
Then you have an interface.
What interface is if you look at your laptop or your computer at the back of it, there's a port where
you can connect your cat five cable.
That's the interface Nikhat.
So Interface always have a Mac address that is a permanent Mac address to your neck associated with
your card.
And this Mac address never changes.
