WHAT IS IP & WHAT IS WORK OF AN IP ?

FRIENDS DO U KNOW WHAT IS IP & WHAT IS WORK OF AN IP ?

IF NO THEN SEE THIS POST

Internet Protocol (IP) addresses are usually of two types: Public and Private. If you have ever wondered to know what is the difference between a public and a private IP address, then you are at the right place.

In this post I will try to explain the difference between a public and a private IP address in layman’s terms so that it becomes simple and easy to understand.What are Public IP Addresses?

A public IP address is assigned to every computer that connects to the Internet where each IP is unique. In this case, there cannot exist two computers with the same public IP address all over the Internet. This addressing scheme makes it possible for the computers to “find each other” online and exchange information. User has no control over the IP address (public) that is assigned to the computer. The public IP address is assigned to the computer by the Internet Service Provider as soon as the computer is connected to the Internet gateway.

A public IP address can be either static or dynamic. A static public IP address does not change and is used primarily for hosting web pages or services on the Internet. On the other hand, a dynamic public IP address is chosen from a pool of available addresses and changes each time one connects to the Internet.

Most Internet users will only have a dynamic IP assigned to their computer which goes off when the computer is disconnected from the Internet. Thus when it is re-connected it gets a new IP.

You can check your public IP address by visitingwww.whatismyip.com

What are Private IP Addresses?

An IP address is considered private if the IP number falls within one of the IP address ranges reserved for private networks such as a Local Area Network (LAN). The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private networks (local networks):

10.0.0.0 – 10.255.255.255 (Total Addresses: 16,777,216)172.16.0.0 – 172.31.255.255 (Total Addresses: 1,048,576)192.168.0.0 – 192.168.255.255 (Total Addresses: 65,536)

Private IP addresses are used for numbering the computers in a private network including home, school and business LANs in airports and hotels which makes it possible for the computers in the network to communicate with each other.

Hide Files in picture

Hide Files in picture

You may have used DOS's command line copy method but you might not have know that we can use Copy command to hide our files behind any picture or any other files. The following post will show you how to hide important files behind any picture or wallpaper.
We will need Win RAR installed for following trick.

Create a RAR of files which you have to hide. ex. "my-files.rar".
Take a picture/wallpaper you want your files to be hidden behind. ex. "lady-gaga.jpeg"
Move both files(myfiles.rar and wallpaper) in a temporary folder; say "d:\temp".
Open command prompt and make your prompt to path "d:\temp>".
Then type following command Carefully;
"copy /b lady-gaga.jpeg + my-files.rar output.jpeg" without quotes, and press enter.
This command will make output.jpeg by combining both lady-gaga.jpeg and my-files.rar files.
If you double click on output file it will open the picture associated with it, i.e lady-gaga.jpeg here, and if you want to open your rar files just open the output files with win-rar application.
