Note 255.255.255.192 or 11111111. 11111111. 11111111.11000000 The two extra bits in field4 can have four values (00, 01, 10, 11), so there are four subnets. Each subnet uses the remaining six bits in field4 for its host IDs, ranging from 1 to 62. Sometimes a subnet mask does not specify any additional network ID bits, and thus no subnets. Such a mask is called a default subnet mask. These masks are: Class A: Class B: Class C: 255.0.0.0 255.255.0.0 255.255.255.0 These are called default because they are used when a network is initially configured, at which time it has no subnets. 135

The two extra bits in field4 can have four values (00, 01, 10, 11),
so there are four subnets. Each subnet uses the remaining six
bits in field4 for its host IDs, ranging from 1 to 62.
Note
Sometimes a subnet mask does not specify any additional
network ID bits, and thus no subnets. Such a mask is called a
default subnet mask
. These masks are:
Class A:
255.0.0.0
Class B:
255.255.0.0
Class C:
255.255.255.0
These are called
default
because they are used when a network is
initially configured, at which time it has no subnets.
