A subdomain can be within the same zone. For as many levels of child or
sub-domains as you want:

zone example.edu { ... }
zone system.subnet.student.class.semester.department.example.edu { ... }

where all intermediate subdomains are part of the example.edu zone.

A (sub)domain can also be larger than a zone. Consider the following zones:

example.com.
lab.example.com.
dev.lab.example.com.

The "lab" domain contains the "dev" subzone as well as its own zone, yet is also a subdomain (and a subzone) of example.com.
