Determining whether devices are on the same subnet
To determine the subnet, the local device’s IP address is
compared
to the remote
device’s IP address (figure A-6). Each address’s octets 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 local
device’s address and the remote device’s IP address 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 local
device’s and remote device’s IP addresses 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
