How Domain Names and the Internet Works

On this article, I am going to explain to you the obvious but surprisingly what most people will admit privately that they really don’t know how domain names and the internet work hand in hand to deliver what you see on your computer screen.

To better understand this; just imagine that Computers talk to each other in a way which has an analogue familiar to all of us: the postal system and the way which it addresses and delivers mail.

As the name would suggest, the internet is a sort of network of networks. These networks are dependent on what are known as their “end nodes” – these would be computers connected to the network. The people using these computers are looking for information.

Given that there are so many millions of computers all connected to the World Wide Web, you might wonder how do computers find each other in order to have this sort of communication between each other?

This function is filled by something which is called DNS, short for the Domain Name System. Any part of a network which will need to send or receive data needs (and is assigned) an IP address. An IP address is an identifier for the computer or network component which identifies it on the network. This address takes the form of a numeric string, looking much like his: 209.115.34.158

Of course while these numbers work well for computers, they are difficult for people to use, let alone remember. For those trying to market something online, this is not ideal. For this reason, a more human-readable naming system has been integrated into the DNS system. For the most part, it is the computers on networks that are named, although routers and other network components will sometimes be named as well.

But surely there are millions of computers throughout the world therefore there needs to be a system in place for matching an IP address to each name in order to keep track of all of these pairs of numbers and names. This is taken care of by a few different parts of the system – name registrars, DNS servers and other network elements.

International bodies such as the IANA (Internet Assigned Numbers Authority) keep track of and provide domain names to website owners. When you register your domain name with any of the domain name company; the company acts as an intermediate between you and these international organizations that maintain and oversee the registration of domain names which in turn lists your name in the DNS server databases.

A DNS server is the system, incorporating both hardware and software which keeps track of the IP/Domain pair and forwards the address from one destination to the next. There may be quite a few DNS servers between your computer and the destination computer you want to send data to or get data from.

If you try to, for instance, load up a website hosted on Site Build It, a DNS server translates (or resolves) the name with the IP address and passes the request along to the IP address you are trying to reach. The data you asked for will be sent back to your computer through the network and shown in your browser.

The process works the same whether you want to communicate between your PC and a server, between one server and another one or any other network communication. DNS servers take domain names and resolve them to IP addresses and forward the requests.

In many cases, DNS servers are a dedicated machine who only perform the function of forwarding and address resolving. The DNS software may also be on a computer which performs other functions.

The process is essential very simple, regardless of how many steps data must pass through. Just like the postal system, DNS translates the name to an address and makes the delivery, with the address being translated back to a name.

Hopefully this article has helped you to understand a little bit more on how domain names and the internet work to enable communication between computers, this will help you especially if you want to start your own internet affiliate marketing business.

How Domain names work

This post will attempt to explain briefly how domain names work once you initiate a purchase or decide to change your name for another.

Each passing day thousands of domain names are registered all the time. At the same time hundreds of names that had previously been registered become available. On the other hand some owners decide to change their domain names. Their are thousands of simple but complex activities and transactions conducted in the domain name industry.

For those who would like to change their domains, there are two steps involved.

1. Releasing the old name.
2. Adopting the new one.

Although this process sounds and seems to be easy, sometimes it is inherent with certain difficulties that you should be aware of in order to prepare for such an eventuality.

Whenever there is a domain change, then thousands of Domain name system (DNS) servers around the globe have to be updated. When this is done a series of complex routines allows this request to be forwarded within the DNS servers.

Now the problem is that when the change of domain name takes place, DNS databases are not all updated instantaneously around the world, chiefly the main reason for this is due to caching.

A cache is a set of stored information that is reused so that fresh information doesn’t have to be communicated with every request for a web page or data.

It takes a while before a cache is cleared, refreshed or expires around the DNS server system.

How Domain Dames work.

It may take anywhere between 24 hours to 48 hours (or even more in case of problems) before all the servers are updated globally. The average time is 6 hours but let me point out that this is just an average; the actual time will vary on a case by case basis depending on a number of reasons.

Because of this a number of things might happen:

1. The IP address pair might not resolve properly and therefore your connection won’t reach the server you want.
2. Your browser will continue to point to the old one or you would receive an error message that such and address does not exist.

Therefore, now that you have a slight understanding on how domain names work, it is important that when changing your domain name, registering a new name or buying another name you should wait for at least two or so days before you start sending/advertising your new website or business otherwise you may end up creating a bad first impression.
