are any guys welcome back in in this video I'm gonna be answered all the questions are you guys still have about IP addressing and subnet masking because yeah we learn the basics of it but now we're looking at this thing and let's hear this is the IP address for my own compute ram thinking okay so somehow I'm sposed to extract the network
IP address at this I mean I on doing just like split right here or 0 ages subnet mask for that's a still kinda confusing and also I mean how many computers are on my network in whenever I make a network how I know what IP addresses I'm supposed to use in you know up effort forget about networking I'm done I'm gonna you know change majors whatever well just a second an hopefully by then that this is a row everything is going to be clear sir member whenever
a computer in other words a router sees this information the first thing that they always do is they converted to binary so
boom there it is in binary and also the subnet mask now I don't need explain how to convert these addresses the binary because we already went over in the last couple videos but there you go son now okay so this is my IP address
in binary format my own personal computer my you know desktop/laptop whatever someone to Facebook and I requested a picture of my ex-girlfriend an Facebook's servers found that picture and it send it back to me
now it's Senate race you to my personal computer but now when that data gets to the router its book meant this IP address and say hey I don't care about your personal IP address I want the network IP address what network do you belong to because thats rhymes was a senate once it's there you know like I said in last video it does its thing
so I'll show you guys how to calculate network IP address and how to extract it from your own personal computers IP address so let me straighten our creeks year and I'll show you guys the easiest way possible is incredibly easy so all you have to do when everyone find out what network IP your computer belongs to
where your own IP address on top in binary format in on bottom break the subnet mask in binary format now whenever both numbers equal one raid1 so 11 okay one anytime you see any 0 whether it's top or bottom or both from rating0 so the only time you're going to have one is when both to make one so this one before make want this one to your own both these equal one 0 111 euro 0 one K this is pretty easy one 01 euro 11 yadda yadda yadda to meet its motto
actually already wrote it out because I don't feel like doing it so I'm just pop it up
and there you go that is your network ID and of course once we have the binary we can converted into a human readable IP address in there you go so right here this if I K drop properly is your networks IP address in this is your own computers
IP address RA so now we know how to figure out the network IP and yet that was a pretty calm asked Rick ball why the heck does that work well let's think about this remember that I told you guys that your IP address is actually broken up into two parts part of it is the network's address and part of it is for the host now we are ready now thanks for something a mask that can be broken up right here which means that the spar on left that's all the network IP address this
hurry here this is for the host individual computers on your network are all gonna have a different one of these numbers
so now that we remember bat we can now understand why this math trick actually works because whenever we have a1 rehear what's so she doing is cocking that part at the IP address so this par here and this partner here or always going to be identical now whenever are some that mass has 0n and pretty much says yeah we'll carry out this part your one
yeah I don't really hear your 0 now your one no don't really care you you're not part of the network IP so forget about you and that is how all these networking vices know exactly what network to send that data to so the last piece of the puzzle i wanna talk how's this art so some server sense and add it to our network has that networking now which computers send it to you how many computers are we allowed to have on our network an most importantly what IP addresses are still issues on our network how the heck are supposed to figure this out it's actually really easy
when we pop this up so whenever we have this example rehear we have 16 use will host that means that we can have 16 computers on our network how do we know this well we know that we have a 32-bit IP address now 28 those bits are designated for the network so we can use those for host that means that we have four bits that can be designated
four devices honor network now remember Kutcher I told you guys there anytime you want to figure out how many values you can have the issues too to the how many bits 4 in the equal 16 so whenever you have four just more places you can have sixteen different combinations oval ones in 000's so that's where we get the 16 different values that we can have for host now remember like a minute ago when I told you guys eat this means that you can have sixteen different computers on your network I lied and that's because you always need a reserved to IP addresses for special occasions the first one is your network IP I mean you just can't have this IP assigned to a device knowing your computers because this is actually the networks address so that takes where one right there an also the very last IP address on your network it's our special broadcasts AP in I don't want to get in there right now because I'm sure overloading you with information right there but again one for the broadcast in one for the network IP address now the rest to those IP addresses hingis assigned to any computers your laptop your phone your you know desktop whatever so in this you starting point rehear in you own 16 IP addresses that follow their so 140 190 141 not one 140 1.2 all the way 215 because remember 00:02:15 that's how we count least 30 instead one so it's not want to 16 so there you go so these are usable host the first IP address that you can actually assigned to a computer is 169 174 to 140 1.1 in you actually have the IP address is alway the 15 but 15 is that special broadcast one so you can use all these from this one to this one right hereso there you go all love that we found out with this bit information pretty stinkin amazing a now I just wanna go over one other example really quick just the pound in your guys brain so whenever you want to figure out the network
IP address are you have to do is compare your IP in your subnet to binary and remember you do that little one trick someone rehear wanna rehear all the way into before though tomb there you go so that's your networks
IP address in binary format let's go ahead and turn them back into a readable format and once we have this information then let me just say okay so this is the network portion of your IP address this is the host and what that means is that we have let's see how many beds 10 so too to the 10 is going to give us their member to reserve to for the network IP and the broadcast and that means that we have all up these IP addresses that we can use for computers on our network so pretty awesome this little chunk of the Internet from here to hear it belongs to us pretty stinkin awesome n you know a I decided to give you guys a homework assignment just make sure that you guys understand everything that's going on
so this is the IP address right here and this is the summit that I gave you your job is to give me the network
I P and also for bonus points we can do Islam gimme be usable host the IP addresses that you can actually a sign to computers and you can just leave your answer in the comments section below an a couple parting thoughts I one point out say that you have a new dress like our 108 die on Arcelik stupid 2.2 da like us 74 now you know a subnet mask is always a buncha ones followed by a bunch as heroes sometimes you may see the notation right after the acute risk people race slash 20 this is just a shorthand version of trading the subnet mask so this means that I'm gonna rate twenty once and then the rest charges euros this is actually called cider notation see II d are and the last thing I wanna point now is the maximum size up your network ID can be 30 bits that's a maximum number of the ones that you could have been
your subnet mask and if you think about it you can have 32 because an IP address is 32 bits and if you made the entire network 32bits te means that you're trying to make a network with no ho Sun'em a network without any computers now if you made it 31 in your reserved one bit for the host that means that you're trying to make a network with only one computer on and that's not a network this is a computer's myself the definition of network is you know computers connected together so you know just some parting words always there for you guys anyways there you go that's your homers Simon leave your answer in the comments section below the first one to get the answer right they actually get no prize but you know it'll be pretty cool also if you guys have any questions at all about anything asked me on my forearm don't really arm check the you to comment sections that much so in my forearm on my website there's a bunch people willing and able to help so there you go she next video
