Notes for Using This Machine Safely

To use this machine, it is recommended you take the following measures, which include:
• Installing this machine in a network protected by a firewall.
• Specifying your private IP address.
• Changing the password for the machine administrator.
• Changing the machine administrator's password can prevent the machine from being tampered by
unauthorized access from the Internet.
Using a Private IP Address
An IP address is a numerical label assigned to devices connected to the network. An IP address that
is used for Internet connection is a "global IP address", and an IP address that is used for network
connection in a local environment such as a company is a "private IP address". If an IP address that
is specified for a machine is a global IP address, unspecified numbers of Internet users can access
this machine, so that there is higher risks of information leakage through illegal access outside from
the environment where this machine is located. If a private IP address is specified for a machine,
however, only users within a local network such as a company LAN can access the machine.
Unless there is any specific reason, specify a private IP address for a machine. An private IP
address can be selected from the following address ranges:
Private IP address ranges
• 10.0.0.0-10.255.255.255
• 172.16.0.0-172.31.255.255
• 192.168.0.0-192.168.255.255
