A sub domain is something that a user can freely add to his already existing domain which is registered with a certified domain agent. While a domain must be something unique, a sub domain does not. The most important thing is that your web host still provides the service after you add your sub domain to your domain. Most of the time, sub domains are very similar to sub folders. These folders are used to organize the website content more easily, especially when it comes to different categories or languages.
There are some exceptions when the search engines are in question. Search engines like Google, for example, are known to recognize sub domains as an independent domain from its primary domain. It is also important to know that every domain has its own accessible record that is public.
This record includes information like domain expiry date and registration, mailing address, contact data and owner name. This is called a Whols record. Its main purpose is to list the contacts and registrants. It is a rule that domain owners must make this personal data available on Whols directories. Anyone who engages a Whols search can find this data. It is used for finding out who is the owner of a certain website or particular registration details.
Now, when someone searches for the domain info, they will be appointed to a forwarding service. This service is done by a proxy server that replaces your data with the data from a forwarding service. This is done when you want to hide your info from the public and it is called a domain privacy. You can hide everything from your name to your phone number or a physical address, even your email. This simply protects you from any abuse of your domain or your personal data. There are a lot of hackers and spammers these days so it is preferable to keep your personal info hidden away from their cyber reach.
There are even companies who are looking for domains with an expiry date that is drawing near so they can send their renewal notices. All they want is you to change your web host and use their services. This is most of the time just a hoax and they will try to appoint you to their search engines and other suspicious services. A domain privacy is the only thing that stands between you and the identity thieves and stalkers who are just waiting for an unsecured domain so they can start using all the available personal data.
It is important how your choose your web host for your site. Checking the customers’ reviews would be the best way to do it. It is important to think of the questions that will give you the right insight about your potential web host. They will be in charge with the whole content of your website or sites, that’s why it’s important.
