Introduction

domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes.

In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a website, or the web site itself or any other service communicated via the Internet.

Most of the people don’t about the term DOMAIN. We are often asked by beginners- what is the domain name? However, many beginners confuse domain name with a website or website hosting service. If you are just starting out, then all these different terms may sound too technical.

What is a domain name? This seems to be such a basic thing, but it’s not always THAT easy especially if you’re a beginner.

Creating a website? You need to get many things in place before it’s up and running. One of the prerequisites is a domain name. So…what is a domain name?

What Is Domain Name?

Domain name is the address of your website that people type in the browser URL bar to visit your website.

A domain name is essentially your website’s equivalent of a physical address. In the same way that a GPS needs a street address or a zipcode to provide directions, a web browser needs a domain name to direct you to a website.

In simple terms, if your website is a house, then your domain name will be its address.

Detailed explanation:

The Internet is a giant network of computers connected to each other through a global network of cables. Each computer on this network can communicate with other computers.

To identify them, each computer is assigned an IP address. It is a series of numbers that identify a particular computer on the internet. A typical IP address looks like this:

66.249.66.1

Now an IP address like this is quite difficult to remember. Imagine if you had to use such numbers to visit your favorite websites.

Domain names were invented to solve this problem.

Now if you want to visit a website, then you don’t need to enter a long string of numbers. Instead, you can visit it by typing an easy to remember domain name in your browser’s address bar.

Domain names serve to identify Internet resources, such as computers, networks, and services, with a text-based label that is easier to memorize than the numerical addresses used in the Internet protocols. A domain name may represent entire collections of such resources or individual instances. Individual Internet host computers use domain names as host identifiers, also called hostnames. The term hostname is also used for the leaf labels in the domain name system, usually without further subordinate domain name space. Hostnames appear as a component in Uniform Resource Locators (URLs) for Internet resources such as websites (e.g., en.wikipedia.org).

Domain names are also used as simple identification labels to indicate ownership or control of a resource. Such examples are the realm identifiers used in the Session Initiation Protocol (SIP), the Domain Keys used to verify DNS domains in e-mail systems, and in many other Uniform Resource Identifiers (URIs).

An important function of domain names is to provide easily recognizable and memorable names to numerically addressed Internet resources. This abstraction allows any resource to be moved to a different physical location in the address topology of the network, globally or locally in an intranet. Such a move usually requires changing the IP address of a resource and the corresponding translation of this IP address to and from its domain name.

Domain names are used to establish a unique identity. Organizations can choose a domain name that corresponds to their name, helping Internet users to reach them easily.

A generic domain is a name that defines a general category, rather than a specific or personal instance, for example, the name of an industry, rather than a company name. Some examples of generic names are books.commusic.com, and travel.info. Companies have created brands based on generic names, and such generic domain names may be valuable.

Domain names are often simply referred to as domains and domain name registrants are frequently referred to as domain owners, although domain name registration with a registrar does not confer any legal ownership of the domain name, only an exclusive right of use for a particular duration of time. The use of domain names in commerce may subject them to trademark law.

A domain name takes the form of two main elements. For example, the domain name Facebook.com consists of the website’s name (Facebook) and the domain name extension (.com). When a company (or a person) purchases a domain name, they’re able to specify which server the domain name points to.

Domain Name Syntax

A domain name consists of one or more parts, technically called labels, that are conventionally concatenated, and delimited by dots, such as example.com.

The right-most label conveys the top-level domain; for example, the domain name www.example.com belongs to the top-level domain com.

  • The hierarchy of domains descends from the right to the left label in the name; each label to the left specifies a subdivision, or subdomain of the domain to the right. For example: the label example specifies a node example.com as a subdomain of the com domain, and www is a label to create www.example.com, a subdomain of example.com. Each label may contain from 1 to 63 octets. The empty label is reserved for the root node and when fully qualified is expressed as the empty label terminated by a dot. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation. Thus, when using a single character per label, the limit is 127 levels: 127 characters plus 126 dots have a total length of 253. In practice, some domain registries may have shorter limits.
  • A hostname is a domain name that has at least one associated IP address. For example, the domain names www.example.com and example.com are also hostnames, whereas the com domain is not. However, other top-level domains, particularly country code top-level domains, may indeed have an IP address, and if so, they are also hostnames.
  • Hostnames impose restrictions on the characters allowed in the corresponding domain name. A valid hostname is also a valid domain name, but a valid domain name may not necessarily be valid as a hostname.

Are Domain Names and Websites separate things?

Think of a domain name as your phone number and a website on your phone. While they are connected, they are separate items.

You can change your phone (website) at any time, and still, keep your existing phone number (domain name), and just connect it to your new phone (new website).

Or, you can move your phone number (domain name) to a different phone service provider (domain name registrar), and still keep it connected to your existing phone (your website).
