Public ip are the ip that can be accessed by every one,ie very user has the access to this ip's.e.g yahoo.com,google.com etc are the pubic ip's.

Private ip's are the ip that can not be accessed by every one,ie they are execively owned by an organization,only the user of that organisation has the access to this ip's.

Range of private IP address are

class A    10.0.0.1    to 10.255.255.254

class B    172.16.0.1 to 172.31.255.254

class C    192.0.0.1  to 192.255.255.254

excluding ips are public ip's.

The class C range of PRIVATE Addresses is WRONG.

The correct range of valid Class C Private IP addresses are:

192.168.0.0 - 192.168.255.255 CIDR: 192.168/16

Please make sure that you confirm before giving some information.

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.

A Public IP address allows a network to be identified on the Internet and is usually the IP address of the device's interface that connects to the Internet, public IP addresses are usually issued by the ISP. Any IP address behind the Public IP address would not be viewable by anyone on the Internet whether they were public or private. Private is actually a range of IP addresses reserved for use on any device behind the Internet connection and was established for good practice.

  

IP Classes and Ranges

 

A-10.0.0.0 - 126.0.0.0       /8

B-128.0.0.0 - 191.0.0.0     /16

C-192.0.0.0 - 223.0.0.0     /24

D-224.0.0.0 - 247.0.0.0                  Used for MULTICASTING

E-248.0.0.0 - 255.0.0.0                  Used for EXPERIMENTAL purposes

 

Private addresses as specified by RFC 1918

 

10.0.0.0/8

172.16.0.0 - 172.31.0.0/16

192.168.0.0/24

-----------------------------

169.254.0.0 automatic private

*** Please note: 127.0.0.0 is reserved for loopback purposes.

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/ .
