TCP/IP
An important protocol used widely on theInternet
A routable protocolSupports communication with UNIX
networks or any other network that workunder the TCP/IP protocol
The base protocol in UNIX networks is TCP/IP
Can be used for configuring peer-to-peer as
well as client-server networks of very largescale

TCP/IP INSTALLATIONAND CONFIGURATION
A two-step process
First, install the protocol With many modern OSs such as Windows
XP, it
is automatically installedSecond, configure its properties
When TCP/IP is automatically installed, theproperties are set to
be obtained from a DHCPserver
However, it is also possible to manually set theproperties

ACCESSINGTHE WINDOWFOR TCP/IP
PROPERTIES
Under different Windows operating systemsthe TCP/IP properties
are accessed indifferent ways The best and the most consistent way
to access
TCP/IP properties Windows is to go through theControl Panel and
then select the Network Icon
Another way to access the properties is to gothrough Network
Neighborhood
Thereafter, select the network properties (Basedon the NIC) and
then then continue to select theTCP/IP properties

TCP/IP CONFIGURATION OPTIONS
Dynamic IP
A DHCP server must be present in the network
to issue dynamic IP
In a number of cases, the MAC address of theclient is registered
to prevent unauthorized
leasing of IP addresses to clients
Static IP
Obtain the IP address specifications from thenetwork
administrator

DHCPAND TCP/IP CONFIGURATION
Without a DHCP server Requires the static assignment of IP
addresses
and properties
The DHCP server need not reside on the same
subnet
With a DHCP server IP addresses etc. are automatically assigned
by
the DHCP server
Select the appropriate option for the TCP/IPaddress to be
dynamically assigned by theDHCP server
