Well, we made it through vlsm. Not bad, not bad at all, we found out what vlsm is. And it was really just changing the subnet mask to meet the needs of the network. That's it. That's all it is. Okay, how many now?
How many IPS do you need? Okay, I need 1000. Okay, we'll put the line right here. I told 1024. So I have 1020 for the party give you a little bit more. But it's not like before where there will give you a whole block of you know, our class default Class B or something like that.
Right? It was there for the purpose, the mechanism to slow down, you know, the death of ipv4. But again, you know, for networking, it's a lot better. You have closer numbers, less routes, things of that nature. And we saw how to calculate Well, we saw the concepts here. All right, that I showed you that a Excel spreadsheet, the concepts of vlsm you know, the little triangle, what have you.
But then we actually did it in Notepad, we calculate it vlsm we had those networks 250 300, what have you, okay, and then we started again from zero. And then we can have the number of holes. And then we saw how we got the broadcast count number, and we added it to the proper octets. And then we saw the range and we put the cider. And then we went from the from the broadcast, that's your last available IP, What's the next one? Boom, that's your new starting point, and so forth.
May see, that's how we did these two topics, but we did a lot, because you saw although you did all those networks, okay. And again, you need to keep practicing and practicing and come up with new networks and come up with new ideas. Okay, in order to create your vlsm network. For certification purposes, you're not going to have to do all that. So, you know, they may put a couple networks and they'll tell you Okay, summarize that. Well, that's summarization, but they may tell you based on this vlsm network so you need to know what they're talking about.
Okay, we'll be there to stay connected together. What will be the end this vlsm network, what will be the best mass as an example? Okay. Oh, sorry. 30 using vlsm, right? Okay.
That's all it really is. Need to Know the concepts of how to calculate that. But that's it. No big deal. No big deal. All right.
See you in the next one.
