Answer / asish mishra
VLSM is used for proper implimentation of IP addresses
without any loss.In real world this is used by the ISP to
Distribute the public Ip when asssigning the WAN links.
Basically companys who requires WAN link we need to use 2
IP addresses ,One at our terminal and another in ISP
terminal.But a single Class C address provides 254 valid
host addressses what to do with rest 252 addresses.Throgh
VlSM we can use it in 2 Valid host per subnet.Rest of all
addresses can also be distributed with a Separate block
size or 6,14,30,62 hst per subnet.

Answer / shahid ahmed
Allows for the creation of efficient, scalable addressing
schemes.
One of the modifications that has helped to bridge the gap
between IPv4 and IPv6 (128bit)
RIP V1 for small networks – RIP V2 scalable by using VLSM
With VLSM, a network administrator can use a long mask on
networks with few hosts,
and a short mask on subnets with many hosts

Answer / ranjeet
vlsm stand for variable length subnet mask. eigrp and rip v2
it supports.it is used to reduced the lack of ip address
after subneting if we want add more depart in org. for that
we have to need second mask so to get new mask we used vlsm

Answer / harekrushna das
VLSM stands for Vairable lenth subnetwork . It bsically
need for the ISP , who used the wan . but its basic found
is as per oure requirement we use the ip address without
any loss or extra ip . so that the VLSM is need.
for subneting follow the CCNA book .
