Classless Inter-Domain Routing (CIDR)

There are diff classes of ip address A(1-126) ,B(128 -
191),C(192 - 223),D(224 - 247)and e (248 - 255) so when u
have a ip address it is alsways in one of thes class.. how
ever lets take a scinerio .. say we have a office where we
need 500 comp and u need to assign ip address to them . ull
choose a class ip adress which hails from (1-126) .. good to
go.... but ull b able to gv 500 diff ip address but ull
waste rest of them .. so in order tosave ip address
classless ip address is used.. where in u dont consider
class as a factor .. .... supernetting also comes into
picture here.. hope this explains u the topic however it a
very broad topic cant be expianed without numbers ...
