Subdomains without TLDs

How do I set up a subdomain without a TLD? I have this set under my main config

<VirtualHost *:80>
    ServerName bbs.67.777.777.777 #fake bc my server can easily be hacked ATM :(
    DocumentRoot /var/www/phpBB
</VirtualHost>

      

        
        
        
      

    

when i goto bbs.serveripaddress i get Address Not Found error. if I put this above my main config it still doesn't work, but the whole site points to / var / www / phpBB instead of / var / www (HUH!?!)

master host v

<VirtualHost *:80>
    ServerAdmin webmaster@localhost

    DocumentRoot /var/www/
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory /var/www/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
        # This directive allows us to have apache2 default start page
                # in /apache2-default/, but still have / go to the right place
                RedirectMatch ^/$ /apache2-default/
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
        AllowOverride None
        Options ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ErrorLog /var/log/apache2/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog /var/log/apache2/access.log combined
    ServerSignature On

    Alias /doc/ "/usr/share/doc/"
    <Directory "/usr/share/doc/">
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from 127.0.0.0/255.0.0.0 ::1/128
    </Directory>

</VirtualHost>

      

        
        
        
      

    

I am using debian box using apache2 if that helps.
