A
Class C Network
IP address 192.0.0.xxx to 223.255.255.xxx
These network addresses are most common and are often used in small companies.
These networks can consist of a maximum number of 254 hosts.
Example: 192.7.1.9 (network 192.7.1, host 9)
The remaining addresses 224.x.x.x - 239.x.x.x are defined as ”class D” and are used
as a multicast addresses.
The addresses 240.x.x.x. - 254.x.x.x are defined as "class E" and are reserved
addresses.
Network Address
The host address with all host bits set to "0" is used to address the network as a
whole (in routing entries, for example).
Broadcast Address
The address with the host part bits set to ‘1” is the broadcast address, meaning “for
every station”.
Network and Broadcast addresses must not be used as a host address (e.g.
192.168.0.0 identifies the entire network, 192.168.0.255 identifies the broadcast
address).
IP Netmask
The netmask is used to divide the IP address differently from the standard defined by
the classes A, B, C. A netmask defines how many bits from the IP address are to be
taken as the network section and how many bits are to be taken as the host section.
When the number of host bits is entered, the VMSE calculates the netmask. The
netmask is displayed in standard decimal-dot notation.
Network Bits Host Bits Netmask
Class A 8 24 255.0.0.0
Class B 16 16 255.255.0.0
Class C 24 8 255.255.255.0
