Understanding the Background of Dynamic DNS

Understanding the Background of Dynamic DNS What is the first thing that comes into everyone's mind when we hear the word DNS or Domain Name Server? Yeah, you are right. A lot of people know a bit or have zero knowledge about it. Well we all have things on our home network we want to access from outside: music collections, game servers, file stores, and more. Dynamic DNS makes it easy to give your home network a memorable and easy to use address.

Dynamic DNS Introduction Basically it is related to the IP address such that every computer attached to the Internet has an IP address.

Name Translation is the process of relating a name (like 'www.google.com') to any IP address (like '74.124.56.163') so that a website that is running locally on a computer can be accessed using an easily remembered name, rather than remembering the IP address number of the computer. Name Translation is implemented via a distributed database known as the Domain Name System.

A Dynamic DNS (DDNS or DynDNS) is a term used to denote the updation that is carried out automatically on Name server in the Domain Name System (DNS). These updation are carried out in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.

The term is used to describe two different concepts.

The first is "Dynamic DNS updating" which mainly focus on carry out updation the traditional DNS records without manual editing. All of these mechanisms are explained in RFC 1236 and use the TSIG mechanism to provide a much more security factor. The second kind of dynamic DNS provides a lightweight and immediate updates often using an update client, which do not use the RFC2136 standard for updating DNS records.
