that identifies the particular network the host belongs to, and
a host ID uniquely identifying the host itself on that network.
A network mask is used to define the network ID and the
host ID. Because IP addresses are difficult to remember,
they usually have an associated domain name that can be
specified instead. See also domain name, network mask.
ISP

usually for a fee.
LAN

network
A group of computers that are connected together, allowing
them to communicate with each other and share resources,
such as software, files, etc. A network can be small, such as
a LAN, or very large, such as the Internet.
network mask
A network mask is a sequence of bits applied to an IP
address to select the network ID while ignoring the host
ID. Bits set to 1 mean “select this bit” while bits set to 0
mean “ignore this bit.” For example, if the network mask
255.255.255.0 is applied to the IP address 100.10.50.1,
the network ID is 100.10.50, and the host ID is 1. See also
binary, IP address, subnet, “IP Addresses Explained” section.
