A domain name contains three levels. The initial stage is the phrase or expression which makes up the initial domain name. The next section of the domain name may be the extension. Samples of popular extensions contain .com, .net or .org. The 3rd part of the domain name, named a next level domain name can be an elective part. Like the very first level domain name, it includes a term or expression to explain whatsoever website it’s going to. But, unlike the very first level domain name, a next level domain name can not accessibility a website alone; it should include the very first level domain as effectively as the extension in their syntax.
