Buying a domain is not a difficult task. Yet, many people do not understand the terms such as domain name, top-level domain and third-level domain. Let’s look at an example in order to understand domain names.
The above address consists of 3 important parts.
- Before the dot.
- Between the dot.
- After the dot.
From right to left, these are the portions of the example.
- .com is the Top-Level Domain (TLD).
- Mybusiness is the Second-Level Domain.
- While www is the Subdomain.
The most important part of this example is the one between the dots “mybusiness”. This is called as domain. For a domain, these are some of the rules you need to follow.
- You cannot put a space while domain naming.
- Domains do not have any case sensitive based letters.
- 63 is the maximum characters used for domain.
- You can include a dash or number on a domain.
- No special character is allowed on domain such as $, ^, % etc.
The combination of domain and top-level domain leads to the formation of domain name. Domain name is also called as “Website Address” in other technical term.
The Sub-domain (part before the dot) however, is the additional part that makes it complicated. A website in reality has many parts similar to domain’s location. These are some examples.
It is important to understand the example before you buy domain for any purpose.
