All righty, welcome back. So what is an IP address? I mean, we see them every day, right? We see this number. I'm sure we're used to seeing it quite a bit. Okay, here we go.

168 You're there. Work. That was I say 100. say this one, right, we see this IP address. What is it? Right? That's you.

That's your device. That's the end device. This is the IP address that has been given to your printer. Okay, to your PC, to whatever end device you should your phone to be issued. This particular IP address. Doesn't matter.

Okay. And then you see something mo we'll get into this later. Now, most of you get a heads up. Okay? All right, that's 255255255 and then zero. Obviously there is a decimal here, it's a little bit difficult when I'm doing it on this screen here, get out the way there.

So this is an IP address is a logical, logical address that will let us know who you are and on what network you will be there. This is really what tells you what network because we have a line that's divided right there. This side right here is your network. This is you right here, hey, I'm one or you're 20 or you're 45 or whoever, but again, is based on this, but we'll get into that a little bit later on. Okay, that's when submitting yourself comes in. But that's what IP addresses and IP address and let's erase all this.

An IP address is what four use black eye, it's four octets Okay, and they're separated by a decimal. So we have we're here unless we do cool. Cool. So, for artists separated by decimal, each octet is eight bits long, which makes an ipv4 address what a 32 bit address, a 32 bit address. So you need to know this. Now this will be a variable different numbers out there, okay?

No greater than 255. Why is that because each octet has a max value of 255 This is the max any one octave can have, you cannot go above 255 per octet, it will be an invalid address. Okay. So we now know that as a logical address, it's a layer three address belongs to a network layer of the OSI, we assign it to end devices internetworking devices, right? We're going to statically or dynamically, right? Doesn't matter how we do it.

All right, but we need to assign it because that's who we are on that particular network. But with these eight bits, and this is crucial for a lot of things, okay. All right. You have you need to know this. You need to memorize this. Okay?

You have 128 6432 16 842 and one those are the bid values on that particular you know that we sent we have four octet separated by a decimal, well that one octet, those are its bid values, and each octet has the same bit values. They don't change, they remain the same. So that Ladies and gentlemen, is an IP version four address. I'll see in the next
