How to Configure IP Address.

One major role of any wireless communication engineer is to make sure that every single computer send and receive information basically known as packet and one way to do this is by assigning IP address to that computer, an IP address can be assign into ways either automatically using the DHCP protocol or statically by manually inputting all parameters into that computer.

In DHCP protocol the router is set automatically to all computers and devices to acquire IP address, Gateways, and DNS automatically all the user need do is to scan and connect to the net work.

Before I go to static IP which is our major objective for this post let take a quick review on certain things like characteristics of routers:

A router has a character that says that if a router receives a packet it will look for the route to exit or send the packet out of the router interface, if theses information are not found in the routing table the router will automatically discard the information, in stressing this a little bit I want to take an example : now assuming your a courier delivery agent and then you have a parse that is in a brown envelop you take it without proper verification just on your way you discovered that there is no receiver or sender address you try opening the envelop only to see 'hello kelly I just want to know how your doing', this will be a confusing condition for the delivery agent and finally he will have to return the parsel back to the company and next the courier company will send this package to their dust bin reason being because their is no source and destination address, this exactly what happens when IP addresses are not configure or not properly configured in a network.

In a simple definition, An IP address is a 32bit address characters specially assigned to host for its identification on a network, example

So in this this case now, there is a destination address so that anything that is meant for this host will delivered to him without stress, to assign an IP address to a host right click on the network icon on the right footer of your desktop,

click on open network and sharing center, this will take to another window, that says view your basic information and set up connections, Using my Window 7 for illustration for this post click on change adapter settings,

another window will appear click on local area connection this will take you to another window also where you will IP versions and protocols you will click on internet protocol version 4 (TCP/IPv4) at this point your close to the achieving your goal all you need do is to click on use the following IP and then put in you sub-netted parameters, DG, and DNS, take a look at these parameters below

This is how to configure static IP on a host in any network.

you will notice that my gateway is this is because it is the address on the router interface which take me to the ISP for me to access the cloud and my internet service and also through which the router will also get back to me with my packages, the DNS which means domain name server translates the host into an IP address, for example from a command line you ping let's say ping gmail.com -t you will get reply containing IP's this is what a dns does we will discus this in full in subsequent posts.

When addressing IP on a network there are certain measures to be taken to make sure your addresses are in are in appropriate scheme compared to the kind of network your have and access given to that host.

Private IP: These are addresses given to organization whose uses nodes in acquiring IP connectivity within enterprise network hence they not routable neither do they cause conflict on the internet.

Public IP: These are addresses that are shared on the internet and distributed in blocks by ICANN.
Loop back addresses : These are reserved addresses use for testing purposes only.
classes of IP: One of the final ways to describe IP's is by using a format to determine the term like class A, :
number of nodes per network : 16,777214.
network ID: first octet.
nodes: last three octet.

 class B, :
number of nodes per network :65,534.
network ID: first two octet.
nodes: last two octet.

 Class C :
number of nodes per network : 254
network ID :first three octet.
nodes: last octet
