right when you click here automatically is coming can you give the 256 here no what it says it's invalid correct why it is in coming to the 256 is 250 page limit why it is coming into 55 millimeter it's outside the range which range which range it is the subnet Mass range correct but it's a default we know the difference there are 56 only allowed from zero from we are counting from 0 to 56 is that two two phaser 256 number how how what is the reason for that why I need to fix under the only range of 255 why can't I know the power 2 to the power to the power what is the two to the four no it's not 2 to the power we using for ipogen 4 right the version we're using for the ipvision 4 what do you mean by ipusion 4 here what do you mean by equation 4 there are four digits foreign in a binary language is it is at 16 bit is it 28 bit is a 32 bit is at 64 bit you know you heard you heard about uh binary number yes yes we use for what is the number zero and one correct we have that is in a bit single bit right yes or no [Music] and you you heard about 8-bit you heard about 16 bit you heard about 32-bit right so what you mean by this now IP version 4 means ipusion 4 means it is equivalent to 32-bit correct so 32-bit it's divided into what is that 4 octet right 4 octet what do you mean by 4 octet each octet each octet which octet must be eight bits right yes or no each octet must be enough four bits so now when we have a IP version 4 32-bit so how do we write it in a IP address 8-bit means how do I write it I can say like that one two three four five six seven eight one two three four five six seven eight one two three four five six seven eight one two three four five six one eight correct [Music] is it my I'm writing correct way yes right so now here is eight bit eight bit here is 8 bit [Music] here is 8-bit and here is 8-bit add one more zero two three four five six seven eight correct now total how many bits are there equal to um correct now now Class A what's the default subnet mask 255.0.0.0 how do I write in a binary number for this eight ones so one one one one one one one one how do you make that one two three four five six seven eight correct dot uh zero zero three four five six seven eight nine two three four five six seven eight now one two three four five six seven eight correct so how do I return for the all four one eight ones what is the basis here now you will be calculating to the binary number there is a calculation right there is uh not to to the power of you can say like that but you can calculate like that here uh calculate here 0 right 2 4 4 6 8 16 because it's late 2 4 x will not come now 16 16 32 32 64 128 right 128 that's all right now if you see rehab now what is the value of if I say all the ones here right we are putting all the ones right one one one one one and one correct what would be the value 128 plus 64 255 total 128 plus 64 128 Plus 64. 32 plus 16 plus 8 plus 4 plus 2 plus 1. what is the value here if you see it comes under 128 plus 64 192 192 plus 32 224 224 plus 16 240 248 to 52 to 54 and the value would be 250 255 right to 55.

tell you I am going to using class a IP address okay you tell me I'll give you that is an IP address range I'll give you IP address range which is 10 Dot 1.1.0 slash 22. find the Network address and the subnet mask can be able to manage if I say slash 22 how do I you know already what do you mean by slash 8 here 16 months right 24 24 ones now when I say slash 22 what do you mean by slash 22 here how many ones you need to write 22 once correct how do I write these 22 ones how do I write 22 once here one two three four five six seven eight one two three four five six seven eight one two three sixteen 17 18 19 20 21 22 right zero zero two three four five six seven eight correct yes correct so what would be that what would be the subnet mask for this how do I write it 255 you know already default perfect now tell me how do I write here um it would be less than 2.5 um 249.

two make sure you should should calculate here there's a calculation how many ones one two three four five six ones are there you need to calculate still here right four three four five six it means 128 plus 64 192 192 plus 30 to 224 224 plus 16 240 248 to 52 your value would be 252.0 bill yeah you go to subnet mask if the if the someone gave you 192.168.10.0 slash 13. what will be the default subnet mask here in this last 13. how many ones [Music] how many ones you need to write 13 months right green ones so 8 already written 9 10 11 12 13 and remainings are 0 correct yes uh 8 9 10 11 12 13 8 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8. so you have written already here 250.

now in this you you know the term networks and how many hosts are coming when you go to the kill two to the power of 22 2 to the power of 8. now same things now you can see eight which is 255 again Dot what would be the value here 128 plus 64 192 192 plus 32 224 224 plus 16 240 and 240 plus 1 to 50 to 48 correct 248 dot 0.0 is that subnet must you go to for the last 13 yes or no sorry what what normally confused me about this is like this 10 now sorry what is that I was I was like this 192.168.10
