*1 This refers to the bits where the subnet mask is 0. If the subnet mask is not set, the following subnet masks are applied depending on
the own station IP address class.
Class A (IP address leading bit string is 0)  Subnet mask: 255.0.0.0
Class B (IP address leading bit string is 10)  Subnet mask: 255.255.0.0
Class C (IP address leading bit string is 110)  Subnet mask: 255.255.255.0
