If use private ip address in your pulic network for example in a web server like ,then no body can access it like yahoo.com or google.com .For a public access to a system ,that system must use a public ip address purchased from iana.org. Otherside if u use a public ip address in your private lan ,for example in your home pc and you try to access to get www.yahoo.com then yahoo will reply to your ip address .if u have used a public ip address for example 64.233.189.204 and it is of google.com then yahoo's reply to you will go to google.com So use this range in your private ip address.

Public IP:
----------
1. Public IP not available in free of cost. If we want to use internet we have to purchase a public IP from ISP

2. Public IP, anybody can access ur network. example. suppose you are using facebook, I want to connect with you, easily I can connect through public IP

3. So in public IP data and information are not confidential


Private IP:
------------
1. In private IP is totally free of cost
2. Same IP can be use by any other different network
3. Outside persons are not entering into one network without any permission
4. So data are secure
5. In private IP, we cannot access internet.
6. Only networking connection possible.

An IP address is an Internet Protocol address. It is used to identify all the websites on the internet. Each IP address is unique and it is separated by periods. For example : 124.2.3.5 . There are two types of ip addresses :
1. Private ip
2. Public ip

Private ip works only in LAN networks . It is also called as internal ip of the computer. To find Private ip address of the computer use the following command :

1. Click start->run->cmd->ipconfig/ipconfig/all

Public ip is used to access the internet. It is assigned by ISP. We cant change it without the corresponding ISPs knowledge. To find out the external ip address visit the site http://www.ip-details.com/ .
