The host address, or the host ID portion of an IP address, is the portion of the address used to identify hosts (any device requiring a Network Interface Card, such as a PC or networked printer) on the network. The network ID, by contrast, is the portion of the address that refers to the network itself.
Find Host ID in Linux
# /sbin/ifconfig eth0
Note:
– The HostID is at the string to the right of HWaddr
