Welcome back everyone into your journey into ipv4. Now, in this particular section, before we get into the nitty gritty of ipv4, one of the things that we're going to talk about first is common hardware used in networking. Sorry about hubs, bridges, switches, routers, whether it be wired or wireless. We'll talk about cabling. All right. So we need to know these things and what they do how they work, more or less not to get too deep into it.

But we need to understand them. All right, because it's not just about assigning IP addresses, or, hey, here's an IP address. You need to understand what device you're working with. So you say, Hmm, what am I putting here? Because we'll learn a whole bunch of things. In this particular course, that we'll get into what is an IP address?

All right. We're going to look at special IP addresses, right? We're gonna look at classes. Yes. And ipv4. We still have classes of IP addresses with ipv6.

We do not well as Then why are you not talking about ipv6? Because this is an ipv4 class. Do you honestly think that everybody out there said, Hey, take off all your ipv4 addresses and just put ipv6 on there? Go ahead. No, all right. You're still running IP for some people are scared to death to go to ipv6.

Okay, so you need to know both. And guess what, your certifications still have ipv4 in them. So you need to know it. Okay. So yes, I believe for those of classes. That was the whole thing.

And then we're going to round off with the subnet mask. And this is key ladies and gentlemen. T. IP four is the subnet mask that will give you the answers to whatever question you may come up on ipv4. All right. So with that said, I'll see you in the next
