The interpretation I run into most often is that it's a seperate segment on
a firewall designated to hold servers that should be accessible both from
the internal network and the internet.
Generaly it's easiest to get this functionality by giving "real" ip
addresses to devices in the DMZ; it is, howeve, not strictly necessary: a
solution that uses some kind of NAT on the firewall to map public IP
addresses to private addresses used on the DMZ can be used as well.
an interpretation where the dmz is just a segment for servers without access
from the internet seems unusual to me.
