Subnetting is a way of dividing a large network into smaller segments, so that most traffic is within individual subnets. The netmask identifies which parts of an IP Address identify the network address, and which parts identify the host address.
The computer sending packets uses the above information to determine whether packets are intended for the local network (subnet), in which case it just sends them, or if they are intended for another subnet (ie non-local traffic) in which case it will send them to the configured gateway.
This PingCOPA network monitoring software utility provides a quick calculation of Subnets, Network Classes and Subnet Masks.
The PingCOPA network monitoring software calculator must first check which class the IP address you specify is in. This is the first part of the displayed Network Class string. See NOTE below for further information on this.
It must then determine which sub class to use. This is either determined by the number of hosts (ie number of IP addresses to be defined in a range) specified in the Hosts field, or the number of sub nets specified in the Subnets field. You must tell the calculator whether to use Subnets or Hosts by selecting a value in one of these fields - the other field will automatically update with the correct value.
Although an IP Address may be (say) Class B, only a small number of IP Addresses in this range may be used by one person or organization, in which case the number of hosts may be limited.
Thus the you may see something like Class B subnetted as Class C in the Network Class box.
