Cisco Confidential 10 IPv4 Subnet Mask Network Portion and Host Portion of an IPv4 Address  To define the network and host portions of an address, a devices use a separate 32-bit pattern called a subnet mask  The subnet mask does not actually contain the network or host portion of an IPv4 address, it just says where to look for these portions in a given IPv4 addressPresentation_ID © 2008 Cisco Systems, Inc.
