Basic TCP/IP Concept / what is IP Address

Presentation




TCP/IP is the certainty standard for PC systems administration and seems to have no challengers

in the systems administration convention stadium. In the event that you are going to work with Windows Server 2003, you

should hope to work with TCP/IP. One of the keys to effectively working with TCP/IP is

understanding the idea of TCP/IP addresses. The fashioners of TCP/IP needed an identi-

fication conspire that was autonomous of any one PC or system gear outline, so

they set up a plan of IP locations.

On the off chance that you've ever surfed the web, you have most likely seen IP addresses (numbers, for example,

192.168.144.77). As you regulate TCP/IP on a system, an impressive piece of your time

will be dedicated to IP address task since IP addresses don't simply mysteriously get alloted

to network has—they must be given through manual arrangement or some other

implies. At the point when a PC is added to a system, it needs an IP location to impart on that

system. At the point when the PC moves to another area, it likely will require another IP address. In the event that

you are simply beginning dealing with an extensive TCP/IP system, you may consider the thought of man-

maturing every one of those locations somewhat overwhelming. On the off chance that you move a DNS server to another subnet, you may

need to reconfigure each customer PC. In the event that you move a customer PC to another subnet, you

might need to overhaul its IP address. This doesn't charm you to street warriors who travel

among a few workplaces, particularly the individuals who are territorial supervisors. In the event that you physically oversee IP

addresses, any change to the system will require a visit to one or more PCs to

upgrade TCP/IP setups—not a cheerful prospect. Luckily, the general population who brought

us DNS to supplant the

has

record likewise concocted an answer for this problem.

DHCP was the Internet group's response to progressively dispersing IP addresses. DHCP

is open and models based, as characterized by the Internet Engineering Task Force (IETF) in

their Requests for Comments (RFCs) 2131 and 2132. (The IETF is the fundamental gauges organ-

ization for the Internet.) This part inspects the essentials of DHCP as it applies to you, the

frameworks head, and how you can utilize it to make your life and your system better.

Understanding DHCP

Open IP locations are enrolled with the Internet Assigned Numbers Authority (IANA) so

that IANA can monitor IP addresses that are being utilized on the Internet. Now and again,

a system is not associated with the Internet and does not have to utilize enrolled open IP

addresses. In different cases, the system is associated with the Internet with extraordinary equipment and

programming that can be designed to permit the system to utilize private locations in conjunction

with location interpretation, ordinarily alluded to as Network Address Translation (NAT). By

utilizing NAT, you can (in straightforward terms) put a whole private system behind a solitary open IP

address. As a case, the association I work for has more than 5,000 hosts on its inward

system. When I or any other individual visits a site on the Internet, we as a whole have all the earmarks of being coming

from a solitary IP address. That is NAT in real life!
