It referring to an Internet address or name, a domain or domain name is the location of a website. For example, the domain name “google.com” points to the IP address “18.104.22.168”. Generally, it’s easier to remember a name rather than a long string of numbers. A domain name can be a maximum of sixty three characters with one character minimum, and is entered after the protocol in the URL, as you can see in the following example.https://www.artechnologygroup.com
Domain names are used to identify one or more IP addresses. For example, the domain name microsoft.com represents about a dozen IP addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL https:artechnologygroup.online the domain name is artechnologygroup.com
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. For example:
· gov – Government agencies
· edu – Educational institutions
· org – Organizations (nonprofit)
· mil – Military
· com – commercial business
· net – Network organizations
Because the Internet is based on IP addresses, not domain names, every Web server requires a Domain Name System (DNS) server to translate domain names into IP addresses.
Domain Name Types
Top-Level Domain (TLD) refers to the suffix or the last part of a domain name. There’s a limited list of predefined suffixes which includes:
- .com – commercial business (the most common TLD)
- .org – organizations (typically, nonprofit)
- .gov – government agencies
- .edu – educational institutions
- .net – network organizations
- .mil – military
TLDs are classified into two broad categories: generic top-level domains (gTLDs) and country-code top-level domains (ccTLDs).
Generic Top-Level Domain (gTLDs) is a generic top-level domain name that identifies the domain class it is associated with (.com, .org, .edu, etc).
Country Code Top-Level Domain (ccTLD) is a two-letter domain extension, such as .uk or .fr, assigned to a country, geographic location or territory.
nTLDs refers to new top-level domain names that are geared towards brands organizations and services, as they’re more customized, flexible and relevant. Examples of nTLDs include “.voyage”, “.app”, “.ninja”, “.cool”, etc.
