Configure settings for using the system while connected in a TCP/IP environment.
In particular, you can check and configure IP addresses, set up DNS servers, and configure IPSec if necessary.
Use IPv4 when you want to set an IP address "xxx.xxx.xxx.xxx" on the system.
[Manual Input]: Manually configure the IP address (if required, you can also configure the subnet mask and default gateway).
[Auto Input]: The IP address is assigned automatically. As such, you do not need to manually set the IP address.
