another class c example




192.200.200.167 / 28


now again count till 24 ...now are left with another 4 bits ... rest is childs play as usual... tick 4 horizontally and 4 vertically in the second table...

after seeing the table and seeing the number under subnets it is 240 and under bits it is 16 .. so simple subnet mask ends with 240 and it has a diff of 16 for every

so our subnet mask is ... 255.255.255.240


subnet we write


so we will start with 0 as usual


subnet--------------firsthost------------lasthost--------------broadcast

192.200.200.0-------192.200.200.1--------------------

192.200.200.16

192.200.200.32

192.200.200.48

etc

etc with increments of 16

192.200.200.160-----192.200.200.161-----192.200.200.174---192.200.200.175

our need fills here


192.200.200.176





hence in this way this can be determined




the crucial one
