Determining whether devices are on the same subnet
To determine the subnet, the IP address of the local device is compared to the IP
address of the remote device (figure A-6). Each octets of each address are compared
or not compared, depending on the value in the related subnet mask octet.
•
If a subnet mask octet contains the value 255, the related octets of the IP
address of the local and remote devices addresses are unmasked.
Unmasked octets are compared (indicated by ? in figure A-6).
•
If the subnet mask octet contains the value 0, the related octets of the IP
addresses of the local and remote devices are masked.
Masked octets are not compared (indicated by X in figure A-6).
If the unmasked octets of the two IP addresses match (indicated by = in figure A-6)
(example 1), the two addresses are on the same subnet.
If the two unmasked fields do not match (indicated by
≠
in figure A-6) (example 2
and example 3), the addresses are not on the same subnet.
