BIND: What Is It And What Does It Do?

If you work on network security for the internet then there is no doubt that you have heard of the name BIND before. It is the program that is installed on mostly all servers that allow them to talk to another server on the internet. It is what is known as a DNS program. I will explain what a DNS program does a little later on in this article. Right now I will give a very brief history on the BIND program. Without it the internet would be very different than what it is today.

BIND started off as a program that was created at the University of Berkley. That is where the name comes from; Berkley Internet Name Domain. The program became so popular because they started to bundle it in the version of the UNIX operating system that also came from Berkley. Once they did that, it started to reach out to other places across the world and it became an internet standard. So now it is time to talk about what it does.


What does BIND do?

As I said before, BIND is a DNS program. A DNS program is also known as a Domain Naming System. It is what allows a Domain to exist. When you type into the browser, you type a name such as That is because you are using a system known as DNS and there is a good chance that you are using BIND. If you didn’t have this program you would instead be typing in a number to get to Google such That is called an IP address. BIND allows you to turn an IP address into a name that is easily read by humans. After it translates that name it then sends it to other servers to tell them about it.

So if you are going to work in computer security then there is a good chance that you are going to interact with a BIND program at some point. Some hackers like to attack BIND faults and at one point it was so bad that they had to rewrite the system. But overall the BIND server has been serving the internet well for a long time.
