my boss want me do build an internal or intranet in our office like mail server web server without
external connection thru the internet(inter-office use only). my question is it possible to build a DNS server without internet conection and it is possible to build a DNS server without registering to the interic ex. "mydomain.com" can my user find my domainname if they email other department like firstname.lastname@example.org
? bottom line... can DNS server work interoffice only?
