3.5.3 Netmask: Number of Bits for Host Part

A netmask defines the number of bits taken from the IP address that are assigned for the host
section.
Note: Class A: 24 bits; Class B: 16 bits; Class C: 8 bits.
The unit prompts for the number of host bits to be entered, then calculates the netmask, which
is displayed in standard decimal-dot notation when the saved parameters are displayed (for
example, 255.255.255.0).
