An IP address is simply an address
on an IP network used by a computer/device connected to that network.
IP addresses allow all the connected computers/devices to find each
other and to pass data back and forth.
conflicts, each IP address on any given network must be unique. An IP
address can be assigned as fixed, so that it does not change, or it can
be assigned dynamically (and automatically) by DHCP.
IP address consists of four groups (or quads) of decimal digits
separated by periods, e.g. 18.104.22.168. Different parts of the address
represent different things. Some part will represent the network number
or address, and some other part will represent the local machine
address. See also IP (Internet Protocol).
