Domain Name Servers
Learn about domain name servers

When you host your website on our high performance web servers, you will need to change the name server information for your domain name. This article explains how to do it, and what it all means.

Domain Name Server Information:
ns1.safewebsite.com    216.15.240.15
ns2.safewebsite.com    216.15.241.15

How to tell your domain name where your website is hosted:
When you registered your domain name, you set a value for your domain name servers, something like the value shown above. Or maybe when you registered your domain name, the system just assigned you a name server value based on the registration service's presets. Or somebody else set it up for you, and then they skipped town when the dot com crash crashed. In either case you will have to contact the company where you registered your domain name and tell them you want to change your "domain name server information" to the values shown above. In many cases you can do this online through the website where you registered your domain name, after logging into their website with your username and password. Sometimes registration companies make it hard to figure out how to do this, because they like to make your life miserable. If you need help in changing your domain name servers, contact us through the tech support link, and we will help you through the process over the phone for a service fee of $25.

What is a domain name server?
A Domain Name Server is a computer that acts like a telephone book for websites on the internet.

Just like a telephone book lists the names of people and their associated telephone number, a domain name server has a list of website names and their associated number.

Humans are better at remembering names, but computers are better at remembering numbers, so we have to have a way to translate the name into a number.

Follow this example to understand how the system works:

TELEPHONE BOOK

INTERNET

You want to call John Smith, who lives in Buffalo, New York, USA, and ask him when the Buffalo Bills might win a super bowl.

So you go to the library and go to the room where all the phone books for the USA are stored.

You ask the librarian for the phone book for Buffalo, NY.

You find the listing for John Smith, and then you see his phone number.

You dial his number, and when he answers you ask him. He tells you in a hushed voice, "I think we'll have to wait until 2004."

You want to find the website amazon.com. So you type the website domain name "amazon.com" into your web browser software.

Your web browser software connects to the name server of your Internet Service Provider (ISP), and looks to see if the value is stored in their temporary memory.

If it is, your web browser is instructed to connect to the internet address number of 207.171.182.16. The amazon.com page is loaded into your web browser.

If it is not in your ISP's local memory, your ISP's domain name server connects to the TOP LEVEL DOMAIN NAME SERVER for all domains ending in .COM

This top level domain name server contains a list of domain names, and which second level domain name server is responsible for handling requests for the domain name that you are requesting.

Your ISP's computer connects to the second level domain name server, and requests the internet address number for amazon.com. Then it stores that value in it's local memory, and returns the value to your computer.

Your computer connects to the internet address number of 207.171.182.16 and the amazon.com web page begins to load. Your computer saves the internet address number of amazon.com in it's local memory, so when you request the next page from amazon.com (for example, when you click on a link to view a book), your computer doesn't have to do the same long process all over again.

Whenever anyone else who is using your ISP to connect to the internet requests a page from amazon.com, they get the internet address number from your ISP's local memory, so they don't have to go through the same long process all over again.

So there. You just helped your neighbor. Now you don't have to feel so bad about running over his cat. :-)

Even though it looks complicated, computers REALLY do make our lives easier. :-)
