Domain Name FAQ

General Questions:

"What is a domain name and how does it work?"

A domain name is a unique name that can be  entered into a browser to resolve the numeric address (called the IP address) of your web site or email server.   It takes the form of a name of your choice coupled with an extension relating to the type of site. Current gTLD ("generic Top Level Domain) extensions are .com (meant for business sites), .org (meant for non-profit organizations), and .net (meant for internet service providers). The original uses of the extensions broke down during the mid 1990s, and there has not been any attempt at enforcement since then. For example, it is now popular for people to register their family names as a .org.  A complete domain name looks like this:

domainname.com

Notice, www is not a part of the name.  The www is a computer resource. In fact it has become a convention used to imply the address of a world-wide-web site. The www is programmed into DNS by your hosting service after you have registered your name.  You are not limited to www.  The beauty of the system is that you may use or assign any prefix, or several, to your domain name which allows you to potentially have an unlimited number of web sites,  email servers, dns servers, or news servers at any number of locations using your single domain name.  Consider the possibilities of names such as sales.domainname.com, home.domainname.com, mail2.domainname.com

In an e-mail address, the domain name follows the @ symbol, so that your e-mail address would look like

A domain name can only be used by the one entity that has properly registered and paid for the use of that name.

"Why should I register a domain name?"

If you use the Internet, you will eventually want your own presence on the world wide web.  The net is experiencing a phenomenal explosion as a primary tool of global communications and information. Already 40% of the American public is on line, and the rest of the world is gaining rapidly. Soon it will be inconceivable for a business not to have at least its calling card available on line.  It's the cheapest and most far-reaching form of advertising that has ever been devised.

The number of personal web site domains is also growing at at an amazing rate.  And it's a small wonder when you consider what you can do with your own domain.  Post your interests and hobbies on the web.  Soon you will begin receiving emails from others around the world who share your interests.  Families researching their genealogy post their web sites and are found by relatives they didn't even know they had.  People are making new friends from the four corners of the world simply because of the ease of communications, and the ability of this tool to virtually eliminate distance.

Of course, you can post a web site on third-party domains such as AOL or Geocities.  However, the web site address might look something like this:

http://members.webservername.net/heartland/meadows/~yourname022/

Doesn't look very easy to  remember, does it? And because of search engine limitations, they don't always index those mega-domains very effectively, making it hard for people to find you via a search. Now, think how much easier it would be to find your website if your address was simply:

http://www.yourname.com

Registering your own domain name gives you presence on the web that is easy to remember, descriptive, and an enhancement to your professional image. And, if you ever need to switch Internet service providers, you can take your domain name with you, whether across the street or to the other side of the world. You'll never need to reprint your business materials, change your email address, or send notifications to your clients.

Even if you don't have a web site ready to go,  you should go ahead and register your domain name while it is still available.  Domain names are  registered on a first come - first served basis, and about 6000 new names are registered every  day. Registering your domain name now will ensure its availability when you are  ready to post your website, and it will prevent someone else from using that name for their domain..

"What are the guidelines for choosing a domain name?"

There are a few guidelines that need to be  followed when deciding on a domain name:

  • The entire domain name (the name and its  extension) cannot be more than 67 characters long.
  • The only characters that can be used in a  domain name are letters, numerals, dashes (-) and the period (.) between the name and its  extension.
  • A domain name cannot begin or end with a dash  (-)
  • You can't have blank spaces within the Domain  Name
  • Don't worry about designating upper-case and  lower-case letters, because domain names are case-insensitive

Also, it is NOT a good idea to  register a domain name that is a recognized trademark or copyrighted name or that  infringes on someone else's legal rights. InterNIC does not screen for names that are  registered trademarks. However, there are documented cases in which individuals who  registered domain names that were trademarks or otherwise copyrighted were sued and forced  to give up their registered domain names.

"What is DNS?"

DNS stands for Domain Name System. It's a database system used throughout the web to map friendly names into IP addresses. A DNS server runs special software to keep track of machine names, web site names, email servers, nicknames, and IP addresses of servers or host machines attached to a particular network, making it possible to access an Internet site by using (with ourselves as an example) CASDNS.net instead of it's IP address 208.33.128.50. DNS also supports separate mappings between mail destinations and IP addresses, and a number of other complex functions.

When you register a domain name, you are asked to supply the names and addresses of two DNS servers where you will have your site hosted.  Every web hosting service has its own DNS servers, and will supply the information to you on request.  It is on these DNS servers that all of the details associated with addresses for your site, your email, etc. are entered and stored.  If you ever change hosting services, you can modify your DNS server information my submitting the new information via our modification form.

As an example, when a person types a domain name into their browser, a query is sent to the InterNIC (government) root servers.  The answer from the root refers the request to the DNS servers you specify at registration (or latest modification).  Those servers in turn send the request to the IP (numeric) address of your web page, which is then displayed in the browser.  The whole DNS process usually takes only milliseconds.

If you have a computer running web server software, with a permanent connection to the internet, and with it's own static (unchanging) IP address, you may want to run your own DNS server using your own domain name.  Affordable software is available on the web via download, the simplest  starting at under $100.  If you wish to do this, you will need to register your server, which is also called a host.  Customers who have registered their domain name through CASDNS may register their hosts here via our Host Registration Form

If you have an internet dedicated web server (as above) and don't feel comfortable with programming your own DNS, CASDNS can provide DNS services for domains registered through us for $20 per year.  You can select that option on our domain name registration form.

"What are the procedures for registering a .COM, .NET or .ORG domain name?"

Any domain name that has not already been registered, ending in .com, .net or .org, may be registered by anyone at any time.  You only need to supply full contact information, have a valid email address, and pay the registration fee.

You are required to name two DNS servers with their IP addresses. You web hosting service will supply you with this information, or you can opt to use our server information for registration purposes at no cost.

The first step is to determine if the name you wish to register is still available. Check the CORE whois database to determine whether a domain name is still available. When you have decided on a domain name that has not been registered already, registration simply involves submitting a simple  form (or using our wizard).   If you want to register a name in a hurry, try our Quick Registration Form.  If you do not wish to check for the availability yourself, just submit your  requested domain name to us and we will check for you.  If the name is already taken,  we will inform you and you will not be charged.  We may inform you of an available name that may be a suitable alternative.

"What's going on with the development of new name extensions?"

Because of the thousands of domain names being registered every day, there has been a concern that eventually there will not be enough domain names available to accommodate the needs of the ever-growing  number of Internet users. To prevent a domain name shortage, the  following seven new extensions were proposed:
         

.firm

for business sites

.shop

for businesses selling products

.web

for personal web sites

.arts

for cultural & entertainment sites

.rec

for recreation & entertainment sites

.info

for information services

.nom

for websites using a family name

For more information on the current of the new extensions, please refer our most up-to-date information on our New Extensions Page.

"How do I transfer my domain to CASDNS management?"

You will simply need to send us a letter of authorization.  CASDNS provides a form that will generate your letter for you.  The fee for domain transfer is $25 , and includes an extra year added to the registration period for your domain. For more information, see our complete instructions at https://www.casdns.net/transfer-domain.htm

"When could there be a problem with a transfer of a domain from another registrar to CASDNS?"

Sometimes the status of a domain does not allow for transfer.  A domain name cannot be transferred until at least 60 days has passed since it was first registered or last transferred between registrars.  Sometimes a domain name is frozen by a registrar for nonpayment of fees, because the name has expired, or because the name may be involved in some type of dispute.  Though we are occasionally able to effect a transfer for an expired domain, a domain holder who wishes to change registrars should make every attempt to do so before the name expires.
