What determines which bits in an IP address represent the subnet, and which represent the host?
A.
Subnet
B.
unicast
C.
netmask
D.
multicast
E.
broadcast
Explanation:
A subnetwork, or subnet, is a logically visible subdivision of an IP network. The
practice of dividing a network into two or more networks is called subnetting.
The routing prefix of an address is written in a form identical to that of the address itself. This is
called the network mask, or netmask, of the address. For example, a specification of the mostsignificant 18 bits of an IPv4 address, 11111111.11111111.11000000.00000000, is written as
255.255.192.0.
