After specifying the settings for TCP/IPv4, follow the procedure in "Settings Common to TCP/IPv4 and TCP/IPv6" to specify the required settings, and the procedure in "Confirming TCP/IPv4 Settings (PING Command)" to check whether the network settings are correct.
To set the IPv4 address prefix: Press [Specify Prefix] → press [Address] → enter the IPv4 address prefix → press [Prefix Length] → enter the prefix length. If data transmission/reception is attempted between the device having the IPv4 address specified in this procedure and the machine, a block log will be generated.
To make it easier to manage TCP/IP settings, we recommend using automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network if your network supports it.
In the Active Directory environment, right-click the icon of the DHCPv4 server you are using → select [Properties]. In the [Advanced] sheet of the displayed dialog box, click [Credentials]. In the [DNS dynamic update credentials] dialog box, enter the user name, domain, and password for the Active Directory. Press [OK] → [Up] → [Up].
If you enter '255' in [Prefix Length], no IPv4 addresses will be set.
If you use DHCP without the DNS dynamic update function, it is recommended that an identical IP address be assigned to the machine at all times. (If the IP address is not identical, the host name for the machine will not correspond to the IP address.) 6.
It takes about two minutes to check whether the DHCP, BOOTP, or RARP settings can be used. If you do not plan to use one of these settings, it is recommended that you turn them off.
If you press [On] for <DNS Dynamic Update>, you can automatically register the IPv4 address, host name, and domain name set for the machine in the DNS server using dynamic DNS updating. A dynamic DNS server is required for using dynamic DNS updating.
