A subnet mask divides a network that uses the internet protocol (IP) addressing scheme into multiple subnetworks. An internet address has two parts: a network address and a host address.The network address defines group of members (hosts, computers, machines) in a network. The host address defines and actual host, computer, or machine that is a member of the network.
It does not require a subnet mask.
If this is a default subnet mask, then it would be a class C subnet mask. If you are subnetting a network and this is not the default subnet mask, then it could be either a class A or class B.
The default subnet mask has a standard size. The custom subnet mask allows you to make subnets that are smaller or larger than the default.
To determine the network or subnet address of an IP address
2 given subnets
255.255.255.0
255.255.255.0
A subnet mask is something that divides the IP address into a host and network. It is a very confusing thing but it will also let you see the IP address of the user.
Subnet mask for the above is 255.0.0.0
if the ip address is 192.168.2.1 then the subnet mask should be 255.255.255.0
The default subnet mask would be 255.255.0.0 for a class B address.
By changing subnet mask..from 255.255.224.0 to 255.255.240.0 Number of subnetworks increase and the number of host in each subnetwork decreases
