What is Domain Name ?
A domain name is your website name. A domain name is the address where Internet users can access your website. A domain name is used for finding and identifying computers on the Internet. Computers use IP addresses, which are a series of number. However, it is difficult for humans to remember strings of numbers. Because of this, domain names were developed and used to identify entities on the Internet rather than using IP addresses.
A domain name can be any combination of letters and numbers, and it can be used in combination of the various domain name extensions, such as .com, .net and more.
The domain name must be registered before you can use it. Every domain name is unique. No two websites can have the same domain name. If someone types in www.yourdomain.com, it will go to your website and no one else's.
A domain name can be purchased through an online registrar such as Godaddy or one of the many domain name resellers. ICANN (the Internet Corporation For Assigned Names And Numbers) authorizes these registrars to sell domain names.
Many WordPress hosting providers such as Bluehost will provide one free domain registration with their packages. You can change the domain name location from one web host to another by changing its DNS settings. DNS settings basically tell the DNS servers which IP address corresponds to that domain name. When you change hosts, your IP address will change because you are changing servers.
There are many different domain name extensions that are available. Some of the most popular domain name extensions are: .com, .net, .org, .info, .edu, .biz. There numerous other country level domains such as .us, .in, .ly, .io, and many more.
Why you need a Domain Name ?
On the Internet, your domain name is your unique identity. Any individual, business or organization planning to have an Internet presence should invest in a domain name. Having your own domain name, website and email addresses will give you and your business a more professional look. Another reason for a business to register a domain name is to protect copyrights and trademarks, build credibility, increase brand awareness, and search engine positioning.
Where can I buy a domain name ?
There are a lot of different domain name registrars out there. A couple of well-known ones include GoDaddy and NameCheap when you buy / register for a domain name, you actually pay an annual fee to the domain name registrar so that the domain name remains registered under your name. When your registration period expires and if you don’t renew, you will lose the domain name as it will be made available for other people to register in the open market.
Fortunately, domain name registrars will email you to remind you that your registration period is about to expire, or they provide you with an auto-renewal option so you don’t have to remember.
