in the classless network,we take a large network and convert into small network using the different subnet mask into a network.
that is called a vlsm.

Answer / vaibhav
VLSM (variable length subnet mask) is ipv6 classless ip
addressing. Use to subnet an already subnettted ip adress.
how to calculate vlsm?
first if you have a topology you must determine which
network have the greatest number of host. then assign it as
the first subnet.
ex: ISP wan = 20 Host
IP AD=192.168.1.0
isp wan have a 20 host so its means
20host delta=32 subnet mask=255.255.255.224
ADD THE DELTA=32 IN THE IP ADRESS :
192.168.1.0
+ 32
-----------
192.168.1.32
configuration:
192.168.1.0/27
192.168.1.32 IS THE BROADACST ADRESS.
