Description
An IP address is assigned to each IP node on a net-
work. An IP address is a 32-bit number that is typic-
ally represented in "dotted decimal" notation con-
sisting of four decimal integers, on the range
0...255, separated by periods. Each integer repres-
ents the value of one octet (8-bits) in the IP address.
Parameters define the four octets of the IP address.

IP address
Subnet masks are used for splitting networks into
smaller networks called subnets. A subnet mask is
a 32-bit binary number that splits the IP address
into a network address and host address.
Subnet masks are typically represented in either
dotted decimal notation or the more compact CIDR
notation, as shown in the table below.
