Describe the concept of Subneting.
Subneting is a process of breaking the network into smaller units. These units
care called as subnets. Here a subnet could be several machines in a single
LAN. Networks using IP can create sub networks of logical addresses. With every
IP address there some of the bits in the machine can be used to identify a
specific subnet. The IP address then contains three parts: the network number,
the subnet number, and the machine number
Explain the advantages of using Subneting.
Advantages of using Subneting:-
-
Easier network management and trouble shooting
-
Routing table’s size is reduced which means faster network transfers
-
Solves network congestion problems:- Since the complete network is divided into
smaller networks
-
Network addresses can be decentralized e.g. the administrator of the network
can monitor the subnet
What is custom Subneting?
Subnets that can be customized; i.e. modifying the dividing point between subnet
ID and host ID to suit the needs of our network. The subnet mask that we use
when creating a customized subnet is, called a custom subnet mask. This custom
subnet mask is used to find the customization.
Explain the importance of increasing and decreasing subnet bits.
Adding 1’s as a bit means increasing the subnets and decreasing the hosts.
Removing or decreasing 1’s means decreasing subnets and increasing hosts. Hence
by increasing or decreasing the subnet architecture can be decided as per
needs.
Why do we need a subnet mask?
A subnet mask allows identification of host part and network part of an IP
address. Subnet mask can be used to find if an IP address is present on a
subnet or not.
