Understanding Domain in General

Understanding Domain

Knowing the domain is very important, because the domain also has an important role in a website. In short, a domain is a website address.

When you see a URL that ends in .id, .com,, that’s what is called a domain.

So, the domain is like the complete address that will take you to the website you want to visit.

Without a domain, internet users must write down their full IP address to be able to visit your website. However, IP addresses are difficult to remember, so they are ineffective to advertise.

So, a domain can also be interpreted as a simple form of an IP address consisting of a combination of complicated numbers, so that visitors will find it easier for you to find your website.
