What does FQDN mean, should I use WWW in my domain?
FQDN stands for Fully Qualified Domain Name.
Refers to a fully qualified domain name consisting of a host and domain name.
The domain name itself is composed of two parts: the second-level domain and the top-level domain.
Thus, in the example of waopress.com, “www” is the host, “waopress” is the second level domain and “.com” is the top level domain. This refers to a complete domain name composed of a host and a domain name.
If you have a very large website or expect your website to grow, you should opt for a www domain. It does not add as much complexity to the name and has some inherent technical advantages.
If you have a small or medium sized website, the use of a www domain is unnecessary. Therefore, it is your personal choice whether you want to opt for a www or non-www domain. Practically, there would be no difference, regardless of which one you choose.
