Domain Structure and Types

[gafimiv406]

A domain usually consists of three main parts:
1. Subdomain (hostname) (e.g. www)
2. Domain name (third level domain) (e.g. example)
3. Top level domain (TLD) (e.g. .com or .jp)

For example, in the domain "www.example.com", "www" is the subdomain, "example" is the domain name, and ".com" is the top level domain.

There are also two types of domains: " own domains " and " shared domains ."

A unique domain can be created by freely combining character strings. Creating a domain that matches your company's brand and services will help increase your company's recognition and credibility.

On the other hand, a shared domain is one that is shared by multiple people. Examples of shared domains include blog service domains (hatenablog.jp, ameblo.jp, etc.) and email service domains (@gmail.com, etc.).

Why having your own domain is important for your website
Having your own domain is important for your company's denmark number data credibility and brand recognition . It gives visitors the impression that you are a trustworthy site and email sender, and helps maintain brand consistency .

In addition, from the perspective of SEO ( search engine optimization ), original domains play an important role . The older the domain registration history, the better, and there are also cases where it is said that search engines will rank a website higher if you set a domain that is easy for users to understand.

When acquiring a new domain, you will need to purchase it from a specialized domain provider . In Japan, the main providers are "Onamae.com", "Sakura Domain", "Xserver Domain", and "Muumuu Domain".

Connecting your own domain to your server
Simply acquiring your own domain will not allow you to publish a pre-created website on the Internet. This is where a "domain and server connection" becomes necessary .

By associating the unique domain you have acquired with the IP address of the server hosting your website pages (setting up DNS records), visitors will be able to view and access your website pages through their browsers.

In addition, when sending mass emails such as email newsletters, a "sender's email address" is always required, so a domain connection between your own domain and the distribution server (or cloud service) must be established in advance.
