FQDN means Fully Qualified Domain Name. It is also sometimes referred to as an absolute domain name.
This is a complete domain name, with a host, all domain levels, and the top-level domain.
For example, in www.your-domain.co.uk:
www is the host
your-domain is the third-level domain
co is the second-level domain
uk is the top-level domain
The FQDN specifies exactly where your domain sits within the domain hierarchy. No other domain name can have its exact same information.
