So we are given an ip address here of 17231 .50 .0 .0 slash 22.
00:09
And we're asked to find some base information based on what we're provided.
00:13
In order to get those pieces of information, we're going to we're going to firstly denote this work with the slash notation to figure out where this network lies and what subnet this begins on, ends on, etc.
00:32
So first we're going to count out 22 bits.
00:35
1, 2, 3, 4, 6, 7, 8, that's class a.
00:40
1, 2, 3, 4, 6, 7, 8, that's b.
00:44
And then 1, 2, 3, 4, 5, 6.
00:47
That's going to put us at 22.
00:49
The rest of our subnet is going to consist of zeros.
00:56
One more.
00:59
Okay, so our delimiter is going to be from here on out, meaning our first two octets are going to be the same.
01:08
So 172 -3100 is going to be the start of our address.
01:17
And we're going to figure out how many networks are going to be a part of this subnet as well as which one are, i, epitalize on here.
01:27
So firstly we're going to calculate the number of networks and to do so we're going to count up the number of bits within this section that are one and take that number to the base or two to the nth power essentially.
01:42
So we count out one, two, three, four, five, six.
01:46
So that's two to the six power is equal to 64 networks.
01:54
Then we have the number of zeros left here and that's going to be 10 so that is going to be 2 to the 10th power equals 10 24 now this would be our network address count except or host address count except we need to subtract two keep in mind each network has to have a network id and a broadcast ip so minus 2 is equal to 10 22 that's our host ip count.
02:25
So that is the number, the numbers we're dealing with in terms of numbers per network.
02:30
So to determine what we need to increment this octet by, we have to take 256 by our network count.
02:39
It's going to be 64.
02:40
And it's going to equal four.
02:43
So each network, we're going to, each network we're going to, each network we're going to, increment the third octet by four.
02:58
So for example, we start out with a dot zero.
03:04
I'm going to construct a table down here.
03:08
So 172 .3 .1 .4 .0.
03:13
It's our next network...
