What is a subdomain?
A subdomain is basically a child domain under the main domain name. For example, videos.infraplex.com is a subdomain of infraplex.com.
Once you register a domain, you have the permission to create subdomains for it by yourself.
Subdomains are commonly used by websites to create additional-sites related to the main site under the same domain name. For example, a business website can create a subdomain for their blog or their online store as store.example.com or blog.example.com
Can I cancel my registration of a domain name?
Infraplex will allow you to cancel your domain registration with one months calendar notice. If you cancel your registration, it will become available for others to register.
Other domain name registrars allow you to simply let your domain registration expire.
In most cases, you will not get any refund for the domain registration. However, some domain registrars do have refund policies which you may want to discuss with them before canceling your registration.
Can I move my website to a different domain name?
Yes, you can. You can point your domain name to your hosting server. You can also keep both domain names pointing to the same website.
However, search engines consider it duplicate content and that will affect your search rankings.
