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.
Netmask: Number of Bits for Host Part (0=default) (0) _
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). The default setting is 0.

Set DNS Server IP Address
The DNS server allows the name of a remote machine to be resolved automatically. The default
is N (No), indicating the DNS server address has not been set. To set the DNS server address,
type Y. At the prompt, enter the DNS server address. If the device is DHCP enabled, the DHCP
server provides the DNS server IP address, which will override this configured value.
Note:
This setting is applicable only in Manual Connection mode.
