by A domain is a specific area of knowledge or expertise. In the context of the internet, a domain is the unique name that identifies a website and is used in the creation of a web address or URL. Examples of a domain name include “google.com” and “amazon.com”. Domains can be registered by individuals or organizations for a fee through a domain registrar.
Inverse domain
Inverse domain refers to the process of finding the domain name associated with a specific IP address. This is done through the use of a Domain Name System (DNS) server, which translates the IP address into a human-readable domain name. Inverse domain can also refer to the inverse function of a domain.
Domain Name System (DNS)
The Domain Name System (DNS) is a hierarchical decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It translates domain names, which are easy for humans to remember, into IP addresses, which are numerical labels assigned to every device connected to a computer network that uses the Internet Protocol for communication.
DNS enables the translation of domain names to IP addresses and it makes it possible for users to access websites and other resources on the internet using human-friendly names instead of IP addresses. DNS works by resolving a domain name to an IP address through a process called DNS resolution, which is performed by a DNS server. The DNS server has a database of domain names and their corresponding IP addresses, and it uses this information to match the domain name to the correct IP address.
Uniform Resource Locator
A Uniform Resource Locator (URL) is a string of characters that specifies the location of a resource on the internet, such as a website or a file. A URL is also commonly referred to as a web address.
A URL typically consists of several parts, including the protocol (such as “http” or “https”), the domain name (such as “google.com”), and the path to a specific resource (such as “/search”). For example, the URL ” https://intactone.com/” specifies the protocol “https”, the domain name ” https://intactone.com/ “, and the path “/search”, along with a query string “q=example”.
URLs can also include additional information such as port numbers, user names, and passwords. URLs are used to access web pages, images, videos, and other resources on the internet. They are also used to link to other resources, such as when a website includes a hyperlink to another page.
How does Domain Name work?
A domain name works by linking a domain name to an IP address, which is a unique numerical label assigned to every device connected to a computer network that uses the Internet Protocol for communication. This linking process is done through the use of a Domain Name System (DNS) server.
When a user types a domain name into their web browser, the browser sends a request to a DNS server to resolve the domain name to an IP address. The DNS server then looks up the IP address associated with the domain name in its database, and returns the IP address to the browser.
The browser then uses the IP address to connect to the web server hosting the website associated with the domain name. Once a connection is established, the browser sends a request for the website’s content, and the web server sends back the requested content, which is then displayed in the browser.
To create a domain name, one must register it with a domain registrar. A domain registrar is a company that manages the reservation of domain names. They are accredited by the Internet Corporation for Assigned Names and Numbers (ICANN), which is the organization responsible for managing the assignment of IP addresses and the management of top-level domains (such as .com, .org, .edu, etc.)
Once the domain name is registered, the registrar will associate the domain name with the IP address of the web server where the website associated with the domain name is hosted. This allows the DNS server to match the domain name to the correct IP address when a user types the domain name into their browser.
Why is a domain name used for an IP address?
A domain name is used for an IP address because IP addresses are difficult for people to remember. They are a series of numbers separated by periods, and it can be hard for people to remember a string of numbers like “192.168.0.1”. Domain names, on the other hand, are easy for people to remember because they are composed of words and/or letters.
Using domain names instead of IP addresses allows users to easily access websites and other resources on the internet. Instead of having to remember a string of numbers, users can simply type a domain name into their web browser, and the browser will use the Domain Name System (DNS) to resolve the domain name to the correct IP address. This allows users to access websites and other resources on the internet using human-friendly names instead of IP addresses.
Additionally, IP addresses can change over time, especially when the website is hosted on a dynamic IP. Using domain names allows the IP addresses to change without affecting the access to the website or the email service or any other service associated to the domain name.
Types of domain
Here are some examples of different types of domain names:
Top-level domains (TLDs):
.com (commercial) – example: google.com
.net (network) – example: example.net
.org (organization) – example: ngo.org
.edu (education) – example: harvard.edu
.gov (government) – example: nasa.gov
.mil (military) – example: army.mil
Country code top-level domains (ccTLDs):
.us (United States) – example: example.us
.uk (United Kingdom) – example: example.uk
.ca (Canada) – example: example.ca
.au (Australia) – example: example.au
.in (India) – example: example.in
Generic top-level domains (gTLDs):
.blog – example: example.blog
.app – example: example.app
.shop – example: example.shop
.online – example: example.online
.xyz – example: example.xyz
Second-level domains:
example in example.com
mysite in mysite.info
Subdomains:
www in www.example.com
blog in blog.example.com
mail in mail.example.com
Wildcard domains:
in example.com will match any subdomain (e.g. a.example.com, b.example.com, c.example.com)
Parked domains:
example.com is owned by an individual or organization, but is not currently being used for an active website.
Redirect domains:
example.com redirects the user to another website or page.
