Attention
Never set all bits to equal 0 or 1 in one byte (byte = 0 or 255). These are
reserved for special functions and may not be allocated. Therefore, the address
10.0.10.10 may not be used due to the 0 in the second byte.
Class A
Class B
Class C
Additional network classes (D, E) are only used for special tasks.
Key data
Each WAGO ETHERNET (programmable) fieldbus coupler or controller can
be easily assigned an IP address via the implemented BootP protocol. For
small internal networks we recommend selecting a network address from
Class C.
Class B: (Net-ID: Byte1 - Byte2, Host-ID: Byte3 - Byte4)
Class C: (Net-ID: Byte1 - Byte3, Host-ID: Byte4)
e.g.:
e.g.:
11000101
110
10110101
10
The highest bits in Class B networks are always ’10’.
Meaning the highest byte can be in a range of
’10 000000’ to ‘10 111111’.
Therefore, the address range of Class B networks in the first byte is always
between 128 and 191.
The highest bits in Class C networks are always ‘110’.
Meaning the highest byte can be in a range of
’110 00000’ to ‘110 11111’.
Therefore, the address range of Class C networks in the first byte is always
between 192 and 223.
