VLSM stand for Variable Length Subnet Mask.VLSM originally
defined in RFC 1812, allows you to apply different subnet
masks to the same class address space.
Remember that the best subnet mask for point-to-point links
is 255.255.255.252(130).
VLSM allows you to use more than one subnet mask for given
class address.Remember the two major advantages of VLSM:
More efficient use of address and route
summarization/aggregation.

Variable Length Subnet Masking - VLSM - is a technique that allows network administrators to divide an IP address space into subnets of different sizes, unlike simple same-size Subnetting.

Answer / ponr277
VLSM is used for to avoid the drawbacks of classful network. For Eg. If you divide two subnets in the network. one network have 30 system and another network have only 10 system the remaining bits are wasted and the scaning time also not quickeer in smallest subnet. to avoid this type of drawback we should use VLSM.

a vlsm is sequence of numbers of varable length that
stremlines packet routing within the subnet of a proprietary
network. a subnet can be geographiclly defined local area
network.alternatively a subnet may define security boundries,
departmental boundries multicast zone or hardware security
