The abbreviated notation of a domain name is DN.
A domain name is the address of a site or set of sites. It consists of 2 parts, the name and the extension. For example, in the domain name wpmarmite.com, wpmarmite is the name and .com is the extension.
Since it is an address, each domain name is unique. It is possible to buy one from an approved registrar after checking that it is available. You are not the definitive owner of a domain name. You buy it for a defined period of time, for example one year. If you want to keep it, think about renewing it
As a general rule, it is best to choose a domain name that is easy to remember, simple to write and relatively short. The more complicated it is, the less visitors will be able to remember it easily and talk about it around them.
When you choose a domain name, you will be offered several extensions. The .com is the most common but you can use . net, .org or .info and many other options. Other extensions are also available and are more or less expensive.
The last point to take into account when choosing your domain name is to check its availability on social networks. Indeed, if the name you want is already taken by someone else, you risk legal proceedings if the person has registered a trademark. Even if it doesn’t always go that far, it is not correct to take someone else’s name.
