A domain name is the core of your online identity. It is the address web surfers use to find your web site. Your domain name is yours entirely because once registered, no other party may use that identity online in that Top Level Domain. Computers on the Internet use IP (Internet Protocol) numbers (e.g., 123.452.06.31) to locate other computers. Internet users would have a difficult time remembering these long strings of numbers to find sites, so Domain names were developed to translate IP numbers into easy to remember domain names.

A domain name works like an address forwarding service. All of your Web site content sits on a computer with a unique address. This is called an IP address. An IP address is made up of a series of numbers, such as 123.23.234.45. Your domain name directs visitors to your site using this IP address.We use domain names instead of IP addresses because most people find it easier to remember a name rather than a series of numbers.

The entity, organization, or individual who is the owner/lease holder of a particular domain name is known as the Registrant. When registering a domain name for a Company or Organization be sure that the Company or Organizations name is listed as the Registrant if you wish for the Company to have control over ownership/lease hold.

An ICANN accredited entity (or an affiliate to such an entity) which acts on behalf of a Registrant regarding domain name registrations or modifications, is known as a Registrar.

If you're thinking about registering more than one domain name, you've got the right idea. Registering and using multiple domain names is great for building your business and can help you create a dynamic online identity. When you register multiple domain names, you can:
Keep your competition from registering a domain name that draws customers to them instead of you;
Promote the different products and services you offer;
Drive more traffic to your Web site;
Enjoy more opportunities to market to--and be listed in--search engines;
Create distinct advertising strategies that reach different target markets;
Provide customers more ways to find you when searching the Internet;
Capture common misspellings of your domain name, instead of sending visitors to an error page;
Protect your brand and online identity from those who may have unsavory purposes.

In the Domain Name System (DNS), the next highest level of the hierarchy underneath the Top Level Domains is second Level Domain. In the example of the domain name YourCompany.net - the “YourCompany” part is the second level domain. Second level domain names are what registrants decide upon and register.

Unfortunately, we are unable to change or edit the spelling of a domain name after it has been registered. We try to register the domain exactly as you enter it. Should the registration succeed, you will be charged, even if the domain you entered was not what you actually intended to type.

DNS stands for Domain Name System. This System translates a domain name such as RegisterFly.com into IP numbers. DNS is basically a piece of translation software which allows humans and computers to easily communicate. The network of computers that constitute the Internet map domain names to their corresponding IP numbers.
The DNS record consists data similar to the following example:
Primary Nameserver: ns3.01isp.com
Primary IP address:   119.146.223.130

Whois is a term referring to a domain name search feature for the .Com, .Net, and .Org database. The Whois can be used to search for the owner/lease holder of any domain name which has already been registered. This is valuable information if you wish to contact the owner of a domain name that may or may not be attached to a functioning web site.

Any public domain registration that you register through us will have your name as the registrant, just as if you had registered it through any other ICANN certified Registrar like Network Solutions/Verisign or Register.com. You will be able to change all four contact fields for the domain whenever you want. You can change the name servers for your domain or use the domain to register your own name servers. We do not charge for any of these services. You are free to work with your domain however and whenever you want to.

We do not purchase domains through Network Solutions, Register.com or any other company. We are a fully accredited Registrar of domain names. ICANN, the governing body of domain names, has approved us as a registrar. Our registration services compete directly with those of Network Solutions/Verisign and Register.com. Our prices for these services are simply better. There are no hidden fees and no gimmicks. We do not make you use our hosting services with your domain name. We are able to offer these prices by accepting lower profit margins than others might be inclined to, and by striving to keep our operations efficient.

Domain privacy is a service offered by a number of domain name registrars. A user buys privacy from the company, who in turn replaces the user's info in the WHOIS with the info of a forwarding service (for email and sometimes postal mail, done by a Proxy server) such as "Domains by Proxy, Inc.

Besides setting up your Web site, there are a number of things you can do with your domain once you register it.Sell it. Domain names can be a great investment. If you have registered a domain name that you are not using, maybe someone else can. Go to the Account Manager and set up a For Sale parked page for your domain name. Don't forget to include your contact information. Protect your brand online. The more domain names you register, the better. Prevent others from registering a similar domain name to yours—just to steal away your customers. What to do with all these names? Forward them to your main domain name. Hold on to it. Maybe you haven’t decided what to do with your new domain name. Don’t worry – there’s no rush. You can leave it parked with us for the length of your registration.

Can I register my company’s or products’ Chinese or Korean or Japanese or other non-English name ending in .com or .net?

Yes. You can register an Internationalized Domain Name ending in .com or .net, if available. So, you can seek to register your business name just as you would write it, complete with Chinese or Korean or Japanese or other non-English characters. Internationalized Domain Names are domain names represented by native scripts defined in unicode 3.2. For example, a Chinese domain name would be followed by .com or .net: 国际化域名.com. This is just one way that .com and .net can reflect your business’ origin and values.

Why do I need an Internationalized Domain Name ending in .com or .net?

It’s simple, an Internationalized Domain Name ending in .com or .net enables you to extend your online identity in China or Korea or Japan and other countries around the world. An Internationalized Domain Name can provide you with a more effective way to reach your target markets in your customers' preferred language and script. They also eliminate the need to translate or transliterate your brand into English characters for use as an Internet address. Furthermore, Internationalized Domain Names ending in .com or .net are based on international standards to help navigate the Internet in non-Ascii and certain non-English languages, such as Chinese, Korean or Arabic, etc.

Different companies provide different price for registering domain, below we will talk about the factors which will influence the price of domain register and where to find a best price for it.
Key Things in Domain registration:
You have no need to spend $35 per year to get a domain name, some very good, reputed, reliable and trusted companies, like www.todaynic.com, will offer you a domain with very low price. You will need to pay an annual fee to the domain register company, so don't forget to renew your domain each year.
The prices of domains are varied based on the domain extensions you register. For domain extension like .com, .net, it will cost you only about $7 each year, but for "mobi" domain extension, you might have to pay out $20 per year. Besides the domain extension, the domain register company from different company will ask for different register fee for the country level domain extension.
When registering domain, you will always be asked about the option for "Domain Privacy Protect", this option will allow you to choose not to open your register information so that people won't find who own the web site via whois. In most cases, I would like to recommend this option for individual, but for the company, it doesn't make sense to hide the register information since you want more people to know who own this site.
