WHAT IS DOMAIN NAME ?
A domain represents a physical point on the Internet, an IP address. Domain names are used to identify one or more. For example, the domain name represents about a dozen IP addresses. Domain names are used in to identify particular .
For example, in the URL http://buihongdiep.com.com/about the domain name is
Every domain name has a suffix that indicates which top level domain (TLD) it belongs to. There are only a limited number of such domains.
.gov – Government agencies
.edu – Educational institutions
.org – Organizations (nonprofit)
.mil – Military
.com – commercial business
.net – Network organizations
.ca – Canada
.th – Thailand
.vn – Vietnam
The Internet Corporation for Assigned Names and Numbers (ICANN) governs coordination of the links between IP addresses and domain names across the Internet. With this standardized coordination, you can find websites on the Internet by entering domain names instead of IP addresses into your Web browser.
Here’s an example: Think of a street address for a house or business — let’s say the White House. The street address, 1600 Pennsylvania Avenue, is an exact location — like an IP address. You might not know the exact street address, but when you visit Washington, D.C., you can tell your cabbie that you want to visit the White House and still get there. This is how a domain name is used: It’s an easy way to reach the exact location of a website without having to remember the numeric address.
A domain consists of, at least, a top-level and a second-level domain. See What are top-level domains (TLD) and country code top-level domains (ccTLD)? and What are second-level domains (SLD) and country code second level domains (ccSLD)? for information on these terms. Domain names must be registered with an ICANN-accredited registrar. We are an ICANN-accredited registrar, and you can register domain names through us.
Many TLDs, also called extensions, can be registered by anyone. The extensions .com, .net, and .org are good examples that anyone can register.
Others, primarily country-code extensions (ccTLDs), have residency requirements — like .eu (representing the European Union) and .vn (representing Vietnam).
Still others, like .aero, .biz, .edu, .mil, .museum, .name, and .pro, are restricted to a certain type of entity or community — like .edu, which is reserved for educational entities and .gov, which is reserved for government agencies.
HOW DOES A DOMAIN NAME WORK ?
Registering a domain name does not automatically activate a website that displays when visitors enter your domain name into a Web browser. The domain name must have a hosted website that includes a numeric address, called an IP address, for visitors to access the website using your domain name.
Your domain name and its associated IP address are stored in a common database along with every other domain and associated IP address that are accessible via the Internet.
When visitors enter your domain name into a Web browser, the browser request uses your domain name to find the domain name’s associated IP address and, therefore, the website. People use domain names instead of IP addresses because it is easier to remember a name rather than a series of numbers.
When you register a domain name, you do not have to host a website. See What do I do with my domain once it’s been registered? for information on other uses for your new domain name.
For new .com and .net domain names and updates, allow up to eight hours for changes to become effective. Allow up to 48 hours for changes made to all other domain name extensions to become effective. This delay is because of the number of networks and agencies involved in the Internet structure. Delays apply to all domain names and registrars. Please allow for this delay when planning websites or configuring a domain name to work with your email.
WHAT IS A DOMAIN NAME SERVER ?
Nameservers are the Internet’s equivalent to phone books. A nameserver maintains a directory of domain names that match certain IP addresses (computers). The information from all the nameservers across the Internet is gathered in a central registry.
Nameservers make it possible for visitors to access your website using a familiar domain name, instead of having to remember a series of numbers.
Nameservers on other networks can access information at the central registry up to 8 hours after registering .com and .net domain names and up to 48 hours for all other domain name extensions. This period is referred to as the propagation period.
The nameservers you use depend on whether or not its hosted and where, as well as whether or not the domain name uses one of our advanced domain name features such as CashParking®, Quick Content, or DNSSEC.
