Difference between subnetting & Vlan??
Answer Posted / ranji2011
Hi Friends,
“Subnetting” allows you to create multiple logical networks
that exist within a single Class A, B, or C network. If you
do not subnet, you are only able to use one network from
your Class A, B, or C network, which is unrealistic.
Each data link on a network must have a unique network ID,
with every node on that link being a member of the same
network. If you break a major network (Class A, B, or C)
into smaller subnetworks, it allows you to create a network
of interconnecting subnetworks. Each data link on this
network would then have a unique network/subnetwork ID. Any
device, or gateway, connecting n networks/subnetworks has n
distinct IP addresses, one for each network / subnetwork
that it interconnects.
In order to subnet a network, extend the natural mask using
some of the bits from the host ID portion of the address to
create a subnetwork ID.
“VLANs” are a mechanism to allow network administrators to
create logical broadcast domains that can span across a
single switch or multiple switches, regardless of physical
proximity. This function is useful to reduce the size of
broadcast domains or to allow groups or users to be
logically grouped without the need to be physically located
in the same place.
