No, you can run BIND (named) without your own domain, just to resolve 
offsite FQNs that your local hosts need to resolve. Just run it and provide 
only the file that identifies root server (on my Debian system, 
/etc/bind/db.root). You do this by configuring named.conf to provide only 
that db file (as a "hint"), probably something like this:

         // prime the server with knowledge of the root servers
         zone "." {
                         type hint;
                         file "/etc/bind/db.root";
         };

If you have a significant number of hosts on your LAN, you might want to 
make this instance of BIND locally (on-LAN only) authoritative for a dummy 
domain that the hosts can use to find each other. (That's what I do here, 
for example.) In that case, the stuff you've seen about using BIND with 
real (registered) domains should guide you.

I offer no recommendation, but I do not do so myself.
