Special IP addresses
(1) All bits are 0 or 1
The IP address 0.0.0.0 is used when you do not know your own IP address or it is
not necessary to inform an IP address to the target.
255.255.255.255 signifies a broadcast address (destination: all devices and PCs
connected to the same network).
(2) Loopback address
This is the address which is used between the programs executed on the same
device (PLC).
The range is from 127.0.0.0 to 127.255.255.255.
(3) Multicast address
This is the address used for communications within a specific group.
The range is from 224.0.0.0 to 239.255.255.255.
(4) Private address
It seems that any IP address can be used when a PC is not connected to the
Internet. However, an address which can be freely assigned is designated for
avoiding a trouble.
This is called a private address.
