3.2 .4 Inte rne t Protocol (TCP/IP)
The Internet Protocol specifies the format of packets, also called datagrams, and the addressing scheme.
Most networks combine IP with a higher-level protocol called TCP, which establishes a virtual connection
between a destination and a source.
The parameters of the Internet Protocol are:
Ÿ DHCP Option – Dynamic Host Configuration Protocol. Eith er enabled or disabled.
Ÿ IP Address – an identifier for a computer or device on a TCP/IP network. The format of an IP
address is a 32-bit numeric address written as four numbers separated by periods. Each number
can be 0 to 255.
Ÿ Subnet Mask – a mask used to determine what subnet an IP address belongs to. An IP address
has two components, the network address and the host address. The first two numbers represent
the Class B network address, and the second two numbers identify a particular host on this
network.
Ÿ Default Gateway – the default node on a network that serves as an entrance to another network.
In enterprises, the gateway is the computer that routes the traffic from a workstation to the
outside network that is serving the Web pages. In homes, the gateway is the ISP that connects
the user to the internet.
