Domain names are used to establish a unique identity.
Businesses, groups and individuals can choose a domain name that corresponds to their name, helping Internet users to reach them easily.
Domain Names are often simply referred to as Domains. Domain Name Registrants are frequently referred to as Domain Owners. 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.
Domain names serve to identify Internet resources, such as computers, networks or services. A text-based label is easier to memorize than the numerical addresses used in the Internet protocols.
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. Examples of generic names: books.com, music.com, and travel.info. Companies have created valuable brands based on generic names.
The Internet Corporation for Assigned Names and Numbers (ICANN) manages the top-level development and architecture of the Internet domain name space. It authorizes domain name registrars, through which domain names may be registered and reassigned.
The domain name space consists of a tree of domain names. Each node in the tree holds information associated with the domain name. The tree sub-divides into zones beginning at the DNS root zone.
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.

Each and every domain name comes with all you need to get online.
- Domain Forwarding and Masking: Direct any domain name you own to your website. Anyone who types that domain name into their browser is taken directly to your website.
- Domain Locking: Domain locking prevents accidental or intentional transfers of domain ownership and stops anyone from redirecting your nameservers.
- Total DNS Control: Manage your domain nameserver (DNS) records and set your email, FTP, sub-domains and website location all from one control panel.
- Change of Registration: Assign your domain name to someone else or change the contacts for your domain online anytime.
- Status Alerts: Monitor the status of your domain and get instant alerts if there’s been a change.
- Auto Renew Protection: No need to watch expiration dates to make sure you renew on time! Auto renew keeps your domains, hosting, website builders, and other products in your name and under your control.
- Special savings apply only to first year of registration. You must purchase entire section to qualify for special savings.
- The final price may differ because of additional sales, fees, and promotions.
- Products will automatically renew until cancelled. You may turn off the auto-renewal feature by visiting your account.
- Change of registration may require a fee for certain domains.
